Njengamanje, abakhiqizi abaningi be-injection mold processing ngokuyisisekelo basebenzisaumjovo we-bakeliteimishini yokubumba kanyeumjovo wepulasitikiimishini yokubumba.Kunomehluko ohlukene phakathi kwemishini yokubumba umjovo we-bakelite ka-Dewei kanye nemishini yokubumba yomjovo wepulasitiki.I-Bakelite yi-PF (i-phenolic resin).I-Bakelite iwuhlobo lwepulasitiki oluthuthukisiwe lwakuqala, olwaqala ukukhiqizwa kwezimboni e-United States ngo-1910. Ake sibone ukuthi uyini umehluko?
Izinto ezisetshenziswayo zokukhiqiza i-bakelite ikakhulukazi ama-phenol nama-aldehydes, kanti i-phenol ne-formaldehyde zivame ukusetshenziswa.Zitholakala nge-polycondensation ngaphansi kwe-catalysis ye-asidi, i-alkali nezinye izisusa.Ukukhiqizwa kwezimboni ikakhulukazi kuhlanganisa inqubo eyomile kanye nenqubo emanzi.
I-Phenol ne-aldehyde ingakhiqiza izinhlobo ezimbili ze-PF ngaphansi kwesenzo se-catalysts ehlukene: enye i-thermoplastic PF kanti enye i-thermosetting PF.Owokuqala ungelapheka ube esakhiweni somzimba kuphela ngokwengeza i-ejenti elaphayo kanye nokushisisa, kanti lokhu kwakamuva kungaba ukwakheka komzimba inqobo nje uma kushisisa ngaphandle kwe-ejenti yokwelapha.
Ukuthi i-pf ye-thermoplastic noma i-thermosetting PF, inethiwekhi yokushintshisana kuphela eyakhiwe ngokuphulukisa ingasetshenziswa.Inqubo yokwelapha iwukuqhubeka kokusabela kwenqwaba ye-polycondensation kanye nokwakheka komkhiqizo wokugcina wenqwaba.Le nqubo ihlukile ekuncibilikeni nasekuphulukisweni kwe-thermoplastic evamile.Ayibuyiseleki emuva, okuhlanganisa kokubili izinqubo zomzimba nezamakhemikhali.
I-PF ingabunjwa ngendlela efana ne-thermoplastic.I-Pf esetshenziselwa ukubunjwa komjovo idinga uketshezi oluhle, ukubunjwa ngaphansi kwengcindezi ephansi yomjovo, ukuqina okushisayo okuphezulu kanye nesivinini esiqinile sokuqina, isicwebezelisi esihle ebusweni bezingxenye zepulasitiki, ukudilizwa okulula futhi akukho ukungcoliswa kwesikhunta.Nokho, ukubumba umjovo nakho kunokushiyeka kwakho.Isibonelo, ukuncibilika kunqunyelwe uhlobo lokugcwalisa, akufanelekile ukubumba izingxenye zepulasitiki ngokufaka okuningi, futhi inombolo enkulu yamasango kanye neziteshi zokugeleza ngemva kokuphulukiswa akukwazi ukuphinda kusetshenziswe futhi kungalahlwa kuphela.
Ngamafuphi, i-thermoplastic PF ingakhiqizwa umshini wokubumba umjovo ojwayelekile, kodwa izimo zenqubo kumele zilawulwe ngokuqinile.I-Thermosetting pf kumele ikhiqizwe umshini wokubumba umjovo okhethekile we-PF (umgqomo nesikulufu kuhlukile kumshini wokubumba ojwayelekile womjovo), futhi isikhunta kufanele futhi sisebenzise isakhiwo esikhethekile sokuklama!
I-Sino Vision Vehicle & Service Co., Limited, etholakala eDolobheni lase-Huangyan, e-Taizhou, igxile ekwenziweni kokubumba umjovo okufana ne-bakelite, ukubumba komjovo we-BMC kanye nokubumba komjovo wepulasitiki okunembayo.Imikhiqizo yokubumba yomjovo we-Bakelite ne-BMC isetshenziswa kakhulu kuzo zonke izinhlobo ze-kitchenware, izinsiza zikagesi ze-electromechanical kanye nezisetshenziswa zasendlini.Le nkampani inethimba eliqinile lobunjiniyela nezobuchwepheshe, elizibophezele ekudaleni imikhiqizo enekhwalithi ephezulu kanye nenani elihle kumakhasimende, elingahlangabezana nezidingo ezihlukahlukene zokucubungula zamakhasimende.
