Indlela Yokwenza Ipulasitiki Ebolayo Ngezinto Zemvelo Ipulasitiki evamile ibilokhu iyingxenye yokuphila kwansuku zonke: ukupakishwa kokudla, izikhwama zokuthenga, amabhodlela, ngisho nezinto zasendlini. Kodwa-ke, naphezu kokusebenza kwayo, ipulasitiki esekwe kuphethiloli ibangela inkinga enkulu—kunzima ukubola, iqoqana ezindaweni zokulahla udoti kanye nolwandle, futhi idala amapulasitiki amancane abeka ingozi ohlelweni lwemvelo. Ngakho-ke, ipulasitiki ebolayo… Funda kabanzi

Inqubo Yokukhiqiza Ipulasitiki Ye-Silicone Nokusetshenziswa Kwayo Ezisetshenzisweni Zobuchwepheshe I-Silicone—ngokuqondile, i-silicone elastomer noma irabha ye-silicone—ivame ukubizwa ngokuthi “ipulasitiki ye-silicone” ekusetshenzisweni kwansuku zonke. Lokhu okubalulekile kuhlukile kumapulasitiki avamile asekelwe ku-petroleum njenge-PE, i-PP, noma i-PVC ngoba umgogodla wayo we-polymer wakhiwe ngamabhondi e-siloxane (Si-O-Si), kune-carbon (C-C). Lesi sakhiwo esiyingqayizivele senza… Funda kabanzi

Izinhlobo Zepulasitiki Ezivame Ukusetshenziswa Embonini Yezokwelapha Nendlela Ezenziwa Ngayo Ipulasitiki idlala indima ebalulekile embonini yezokwelapha ngenxa yokuthi ilula, iyaguquguquka, ayibizi kakhulu, futhi ayinamagciwane. Kusukela kumapayipi e-IV kanye namasirinji kuya ezikhwameni zegazi kanye nezitsha zesampula—amadivayisi amaningi ezokwelapha esimanje ancike ezintweni ze-polymer. Kodwa-ke, akuwona wonke amapulasitiki afanele izidingo ezithile… Funda kabanzi

Indlela Yokwenza Amapulasitiki Ahlanganisiwe Nokusetshenziswa Kwawo Embonini Yezimoto Amapulasitiki ahlanganisiwe ayizinto ezihlanganisiwe ezenzelwe ukufeza izakhiwo eziphakeme uma kuqhathaniswa namapulasitiki ajwayelekile. Ngokuvamile, amapulasitiki ahlanganisiwe enziwa ngokuhlanganisa i-polymer matrix (ipulasitiki njengesithako esiyinhloko) nokuqinisa njenge-glass fiber, i-carbon fiber, imicu yemvelo, noma izinhlayiya zamaminerali. Umphumela uba yinto eningi... Funda kabanzi

Amasu Okubumba Ngesibhamu Ekukhiqizweni Kwepulasitiki kanye Nezinhlobo Zepulasitiki Ezisetshenziswayo Ukubumba ngesibhamu kungenye yezindlela zokukhiqiza ipulasitiki ezisetshenziswa kakhulu ekukhiqizeni imikhiqizo engenalutho efana namabhodlela eziphuzo, amathini ejerry, amajagi egaloni, amathangi amancane, amathoyizi, ngisho nezingxenye ezithile zezimoto. Le nqubo isebenzisa umoya ocindezelwe "ukuvuthela" ipulasitiki eshisayo, ethambile ezindongeni zesikhunta. … Funda kabanzi

Ukuqhathaniswa kwe-Polyethylene kanye ne-Polypropylene Plastics I-Plastic isibe yingxenye ebalulekile yempilo yanamuhla ngenxa yezakhiwo zayo ezilula, ezihlala isikhathi eside, neziguquguqukayo. Phakathi kwezinhlobo ezahlukene ze-plastiki ezitholakala kabanzi emakethe, i-polyethylene (PE) kanye ne-polypropylene (PP) yizinto ezimbili ezisetshenziswa kakhulu. Zombili zingamalungu omndeni we-polyolefin, okuyi-plastics eyakhiwa… Funda kabanzi

Indlela Yokwenza Ipulasitiki Ye-Resin kanye Nokusetshenziswa Kwayo Embonini Yokwakha Imboni yepulasitiki ikhule ngokushesha selokhu yethulwa ekuqaleni kwekhulu lama-20. Uhlobo olulodwa oludumile lwepulasitiki olunezinhlelo eziningi, ikakhulukazi embonini yokwakha, ipulasitiki ye-resin. Lesi sihloko sizoxoxa ngendlela yokwenza ipulasitiki ye-resin nokuthi le nto isetshenziswa kanjani ezicini ezahlukene… Funda kabanzi

Izinhlobo Zepulasitiki Ezisetshenziswa Ekwenzeni Amathoyizi Nokuthi Akhiqizwa Kanjani Amathoyizi abe yingxenye ebalulekile yentuthuko yezingane kusukela ezikhathini zasendulo. Ngokuthuthuka kobuchwepheshe kanye nesayensi yezinto zokwakha, ipulasitiki manje isibe yinto eyinhloko ekukhiqizeni amathoyizi. Lokhu kungenxa yezinzuzo zayo ezifana nokuguquguquka, amandla, kanye nekhono lokuba nombala ogqamile. Lesi sihloko sizongena ngokujulile... Funda kabanzi

Inqubo Yokukhiqiza Ipulasitiki ye-Urethane Nokusetshenziswa Kwayo Embonini Yefenisha Isingeniso Ipulasitiki ye-Urethane, noma i-polyurethane, iyinto enezinhlobo eziningi zezicelo ezimbonini ezahlukene, kufaka phakathi imboni yefenisha. Le pulasitiki yaziwa ngokuguquguquka kwayo, ukuqina kwayo, kanye nezakhiwo zayo zokusebenza okuphezulu. Lesi sihloko sizoxoxa ngenqubo yokukhiqiza ipulasitiki ye-urethane kanye nokusetshenziswa kwayo okuhlukahlukene embonini yefenisha… Funda kabanzi

Amasu Okubumba Ngemijovo Ekwenziweni Kwepulasitiki Nezinhlobo Zepulasitiki Ezifanele Ukubumba ngemijovo kungenye yezindlela zokukhiqiza ezivame kakhulu ezisetshenziselwa ukukhiqiza inani elikhulu lemikhiqizo yepulasitiki ngokusebenza kahle kakhulu nangezindleko eziphansi.
