Esikhathini esingeside esidlule, unjiniyela wangibuza:
Banegiya le-POM, futhi inqubo yokuqinisekisa yokuqala iqhubeke kahle.
Kwenziwa imijikelezo emibili yokuhlolwa kokugqokwa, eveza izinguquko ezincane zobukhulu kanye nesimo esihle kakhulu sendawo, okuqinisekisa ukuthi okokusebenza akubonisi izinkinga ezinkulu zokuguga.
Kodwa-ke, phakathi nokuhlola{0}}ubude bokuphila komshini kwakamuva owenziwe ngemva kokufinyelela cishe imijikelezo engu-200,000, amasampula ambalwa aqala ukubonisa ukuphuka kwamazinyo ezindaweni ezingaguquki ngendlela emangalisayo.
Okwamanje kunenkulumompikiswano ethile emphakathini: abanye bathi ibangelwa ukucutshungulwa kwengcindezi, abanye ngenxa yamaphutha esakhiwo, kanti abanye basola ukuhluka kwamaqoqo wezinto ezibonakalayo.
Ubuze umbuzo omuhle kakhulu-
Uma okokusebenza bekunezinkinga ngempela, kungani ukuhlolwa kokugqoka kwangaphambilini kuveze imiphumela emihle kangaka?
Empeleni lolu wudaba olujwayeleke kakhulu, futhi amaqembu amaningi angena kulo.
Okukhomba kukho ngempela akukhona ukungafani kwepharamitha ethile, kodwa umbono oyiphutha wokuqonda.
Kungani into ebonisa ukumelana nokugqokwa okuhle kakhulu iba sengozini yokukhathala ngaphansi-kwezimo zokusebenza zomhlaba zangempela?
01
Abantu abaningi bathola "uhlobo lwenkinga" olungalungile zisuka nje.
Lapho abantu abaningi behlangabezana nencazelo "ukuguga okuphansi + ukuphuka okulandelayo," ukusabela kwabo kokuqala ukuhlonza okungavamile.
Ingabe le nqwaba yezinto azinzile? Ingabe zikhona izinkinga ngokucubungula? Noma ingabe izimo zokuhlola azihambisani?
Kodwa uma udiliza inkinga, empeleni uzoqaphela ukuthi...
Ukugqoka nokukhathala ngokuyisisekelo akuzona isigaba sezinkinga ezifanayo.
I-Wear, empeleni, iyinto engaphezulu.
Ungacabanga ngakho njengendawo ebonakalayo "esikwa" futhi "iklwejwa".
Yiziphi izinto ezidingekayo ukuze umelane nale nqubo?
Ilula: iqinile, iminyene, futhi kunzima ukuyisika.
Okucashuniwe: Ucwaningo kanye Nezimpawu Zezindlela Zokugqoka Eziyi-Abrasive
Njengoba ubona,{0}}izinto eziningi ezingezwani ezigqokwayo zabelana ngalezi zici:
Ubucwebe obuphakeme
I-modulus ephezulu
Amandla aphansi angaphezulu (anezici zokugcoba)
Ngamanye amazwi, ukuhlolwa kokugqoka okulandelayo:
Ingabe ubuso bungakwazi ukumelana nomonakalo wangaphandle?
Kodwa ukukhathala kulandela umqondo ohluke ngokuphelele.
Ukukhathala kwenzeka ngaphakathi kwempahla futhi kuyinqubo enqwabelanayo.
Ukuhlanganyela kwegiya ngalinye empeleni kuwumjikelezo omncane wokugoba nokwelula.
Ilungele ukubukwa okukodwa, kodwa inkinga ...
Lesi senzo sizophindwa ngamakhulu ezinkulungwane noma ngisho nezigidi zezikhathi
Kwenzekani ngaphakathi kwento phakathi nale nqubo?
Iketango lamangqamuzana linwebeka ngokuphindaphindiwe futhi liphindaphindeke.
Ukuwohloka okungabuyiseleki emuva kwenzeka ezifundeni zendawo.
Amaphutha amancane kancane kancane akhula abe imifantu.
Ekuqaleni, ngeke uqaphele izinguquko.
Kodwa uma ukuqhekeka kukhula kuze kufike kusayizi othile obalulekile-
Ukubonakaliswa okukhulu: ukugqashuka okungazelelwe.
Ngakho-ke, inkinga eyinhloko akuyona "kungani iphukile," kodwa kunalokho:
Ukusebenzisa "ukuhlolwa kokugqoka" ukuze uhlole isimo sokusebenza "sokukhathala-okugcwele" zisuka nje akufaneleki.
02
Kungani "ukumelana nokuguga okuthuthukisiwe" empeleni kuholela ekuhlulekeni kokukhathala okuvamile?
Uma usuhlukanise kahle izinkinga, uzobona into ephikisana nokuqondisisa kodwa ivame kakhulu phakathi-nezimo zokuthola amaphuzu aphezulu:
Izindlela eziningi zokwenza ngcono ukumelana nokugqokwa ziphazamisa ukumelana nokukhathala kwempahla.
Lokhu akukhona ukuqondana; kunqunywa ngesakhiwo.
1. Ukuphakama kokukhanya kwekristalu, amasegimenti amaketango aya ngokuya ahamba kancane.
Kungani izinto ezifana ne-POM, i-PBT, ne-PET zibonisa ukumelana nokugqokwa okuhle kakhulu?
Amaketanga e-molecular ahlelwe ngendlela ehlangene kakhulu futhi{0}}nesakhiwo esichazwe kahle.
Kunzima kakhulu kubantu bangaphandle ukungena kuleyo ndawo.
Kodwa yilapho inkinga ilele.
Lapho ingaphansi kwengcindezi yezikhathi ezithile, okokusebenza kufanele kwenze umsebenzi owodwa:
Amandla akhululwa ngokunyakaza okuncanyana kwamaketanga wamangqamuzana.
Kodwa-ke, inkinga-yesakhiwo secrystallinity ephezulu ithi:
Ingxenye iboshiwe.
Ivolumu yamahhala incane.
Cishe asikho isikhala sebhafa endaweni
Umphumela uthi:
Uma amandla angaphandle esetshenziswa, ayikho indawo yokuthi ahlakazeke-ngalokho agxila kuphela ezigabeni ezithile zeketango -futhi abangele ukuthi iketango eliyinhloko linqamuke.
2. Isigcwalisi sivame ukubhebhethekisa inkinga.
Onjiniyela abaningi bokwakha bakholelwa ngokunembile ukuthi:
Ngokumelana nokuguga → Engeza isigcwalisi esiqinisayo
Isibonelo, i-fiberglass, i-carbon fibre, nezimpushana ezingaphili.
Esikhathini esifushane, le ndlela izwakala:
Ingaphezulu liqinile
Ukumelana nokuklwebheka okuthuthukisiwe
Kodwa kwenzekani kulezi zakhi ngaphansi kwezimo zokukhathala?
ukukhulisa ukucindezeleka
Isizathu silula:
I-resin "ikhubazekile".
Isigcwalisi "empeleni{0}asikhubazeki".
Ngaphansi kokulayisha okuphindaphindiwe, isixhumi esibonakalayo phakathi kwezingxenye ezimbili sihlangabezana nengcindezi enkulu yokugunda.
Kwenzekani ngokuhamba kwesikhathi?
I-interface delamination
Yakha ama-microholes
I-crack iqala ukusabalala kusukela emaphethelweni okugcwalisa.
Okokugcina, lokho okubonayo endaweni ephukile akuyona ukuphuka okufanayo.
Kunalokho, kuyisimo esivamile sokufa kokukhathala okwenzeka ngaphakathi.
Ukufingqa lesi sigaba, singafingqwa ngomusho owodwa:
Uhlose ukwenza okokusebenza "kungaklwebheki-kakhudlwana" futhi "kuqine," kodwa ukumelana nokukhathala kudinga ngokuqondile ukuthi "kushintshe futhi kukwazi ukushabalalisa amandla."
03
Lokhu kungqubuzana kungaxazululwa kanjani ngokombono wobunjiniyela?
Uma izingxenye zokukhiqiza ezifana namagiya, ama-bearing, noma amajoyinti ashelelayo, izidingo zekhasimende ngokuvamile ziqondile:
Akumele ilimale noma iphuke!
Ngakho nansi inkinga:
Singakuthola kanjani ukulingana phakathi "kokuqina" kanye "nokuqina"?
Indlela 1: Esikhundleni sokwandisa ubulukhuni kuphela, qala ngokugxila ekwehliseni ukungqubuzana.
Uma ugxilisa yonke imizamo yakho "ekuthuthukiseni ukumelana kwempahla ekusikeni",
Kulula ukuqondisa isistimu kumzila "wokuqina okuphezulu → ukukhathala okuphansi."
Zama indlela ehlukile:
Esikhundleni sokumelana nokungqubuzana ngokuqondile, nciphisa ukungqubuzana.
Kufanele kwenziwe kanjani ngempela lokhu?
Engeza isigaba sokuthambisa esisekelwe ku-silicone{0}
Engeza i-ultra-high molecular weight PE micro-powder
Ukwakha isistimu yokuzigcoba{0}}
Izici zalezi zinto yilezi:
✔ Ayikhulisi kakhulu i-modulus
✔ Nokho, ingenza ungqimba oluphansi lokugunda ngaphezulu
Umphumela uthi:
Ingxenye yamandla angaphandle "iyashelela" kunokuthi "ingene phakathi".
Umonakalo obangelwa ukukhathala awubalulekile kangako.
Indlela ②: Yakha "isakhiwo sokusetshenziswa kwamandla" kunokuncika kokubalulekile okukodwa
Yilapho kanye izitshalo eziningi ezishintshayo zibonisa khona ubungcweti bazo bangempela bezobuchwepheshe.
Umongo awuwona "更强," kodwa kunalokho:
Nikeza isikhala ngaphakathi kokubalulekile kokuchithwa kwamandla.
Indlela ejwayelekile yile:
Njengesistimu ye-alloy, isibonelo i-POM/TPU
I-POM inikeza ukuqina nokumelana nokugqoka.
I-TPU inikeza ukunwebeka kanye nokuchithwa kwamandla.
Lapho i-crack isakazeka:
Uma sekuhlangatshezwane nesigaba esiguquguqukayo...
Amandla amuncwa.
Imifantu iyanqanyulwa noma iqedwe.
Ungadela inani elincane lokumelana nokugqoka.
Nokho, lokhu kubangele ukwanda okukhulu kwesikhathi sokuphila ngenxa yokukhathala.
Indlela yesi-3: Uma isabelomali sivuma, sebenzisa izinto ezinesakhiwo esifanele ngqo.
Ezinye izinto ngokwemvelo zixazulula lokhu kungqubuzana ngesakhiwo sazo samangqamuzana.
isibonelo PEEK.
Isici sayo esichazayo akusona "isikhombi esisodwa esidlulele kakhulu."
Kunalokho, inalezi zimpawu zesakhiwo ngesikhathi esisodwa:
Amayunithi aqinile (izindandatho ezinephunga elimnandi, amaqembu e-ketone)
Ibhondi eguqukayo (ibhondi ye-ether)
Umphumela uthi:
Kokubili kuqinile futhi{0}}okungagugi
futhi ikhombisa ukuhamba kwezigaba ezithile
Ngakho uzothola ukuthi:
Izingxenye eziningi-eziguqukayo ezisezingeni eliphezulu (ezisetshenziswa kwezokundiza nezinhlelo zokwelapha),
Ekugcineni, ngemva kokuzungeza emuva, sibuyela kulezi zinto.
Akukhona ukuthi kuyabiza, kodwa ngoba:
"Iziphambeko zesakhiwo" zezinto ezingabizi kunzima ukuzinxephezela ngokugcwele ngokwakhiwa kukodwa.
Inkinga eyinhloko ngalolu hlobo lwenkinga ayikona "ukusebenzisa izinto ezingalungile," kodwa kunalokho:
Isistimu yokuhlola isetshenziswe ngokungalungile.
I-Wear ukusebenzisana kwamandla phakathi kwezindawo.
Ukukhathala kuwukunqwabelana kwamandla angaphakathi.
Uma ugxile kuphela ekwandiseni imethrikhi eyodwa ngaphakathi kwe-TDS,
Kulula ukufinyelela ukuphelela endaweni eyodwa kuyilapho ulahlekelwa ngokuphelele ukulawula kwenye.
Onjiniyela abanolwazi lwangempela abagxili "ekwenzeni kahle imethrikhi eyodwa"; esikhundleni salokho, bahlose:
Thola iphoyinti lebhalansi phakathi kokuqina, ukuqina, ukungqubuzana, nokushabalala kwamandla okuqinisekisa{0}}ukusebenza kwesikhathi eside.
Uma uke wahlangabezana nalokhu:
Ukuhlolwa kokuqala kwaqhubeka kahle; nokho, kwaphakama izinkinga mayelana neminyaka yokuphila komkhiqizo lapho usuqalile ukusetshenziswa.
Ikakhulukazi leyo-
Isimo lapho "ibingadingi noma yikuphi ukugaya, kodwa isaphuka."
Lokhu cishe akukhona ukuqondana nje, kodwa ukukhathala okuvamile{0}}okubangelwa ukwehluleka.
Bhekisisa kahle ukuphuka ngaphansi kwesibonakhulu-impendulo ngokuvamile isivele ikhona.
