Kutheni ukhetha i-POM yensimbi yeLathe?

I-Pom yomdyarho ye-set yensimbi ye-crystalline yepleyiti yenqaku elibonakalayo. Nje ukuba inqaku lokunyibilika lifikelelwe, i-viscosity ye-velososity inyibilika ngokukhawuleza; Xa iqondo lobushushu lidlula umda othile okanye inyibilike ishushu ixesha elide, iya kubangela ukungavisisani.

Ngapha koko, ikwanemisebenzi elungileyo. Yeyona nto inzima kwi-thermoplastics. Yenye yeentlobo ngeentlobo zeepropathi zoomatshini ekufutshane nentsimbi kwizinto zeplastiki. Amandla ayo angamathondi, ukugoba amandla, ukungcungcutheka, ukunyangwa okungapheliyo, ukunxiba umbane ukusebenzela kulungile, kwaye kunokusetyenziselwa ixesha elide phakathi kwe-degrees ezingama-100.

I-Pom yomdyarho we-seti yentsimbi inamandla ne-elastiki, kwaye isenokuba nokunganyangeki okuhle, uzinzo lwejometri kunye nokungaxhathisi bempembelelo nakumaqondo obushushu aphantsi.

Zombini izinto ze-homollymer kunye nezixhobo zeCopolymer ziyafumaneka. Izinto ze-homollymer zinokufumana ixesha elilungileyo kunye namandla okudinwa, kodwa akukho lula ukucutha; Izixhobo ze-copolymer zinozinzo ezilungileyo ze-subrm, uzinzo lwekhemikhali kwaye kulula ukuziqhubela phambili; Zombini izinto ze-homollymer kunye nezixhobo ze-copolymer zizixhobo zekristali kwaye azifumani mthethweni.

Inqanaba eliphezulu le-crystalty ye-Pom yokugqatselwa kweeLawuli zentsimbi zikhokelela kwireyithi ephezulu ye-shrinkige, enokufikelela kwinqanaba le-2% ukuya kwi-3.5%. Kukho amaxabiso ahlukeneyo e-shrinkage kwizixhobo ezahlukeneyo zoqeqesho.
