Enjeksiyon kal\u0131plama i\u00e7in yayg\u0131n olarak kullan\u0131lan plastikler<\/span><\/h2>\n

Plastic materials commonly used for manufacturing injection molding: ABS, PP, PET, PMMA, PE, PVC, PC, PS, etc. The characteristics of each plastic material are different, and the injection molding process is also different. <\/p>\n

\u00dcr\u00fcn\u00fcn \u00f6zelliklerine, \u00e7evrenin kullan\u0131m\u0131na ve gereksinimlerin di\u011fer y\u00f6nlerine g\u00f6re farkl\u0131 plastik malzemeler se\u00e7memiz gerekir.<\/p>\n

Bunlar sekt\u00f6rde kullan\u0131lan ilk alt\u0131 malzemedir: Polipropilen (PP) Akrilonitril B\u00fctadien Stiren (ABS) Poliamid (Naylon) Y\u00fcksek Yo\u011funluklu Polietilen (HDPE) Polikarbonat (PC) ABS + PC Kar\u0131\u015f\u0131m\u0131 (\u00e7o\u011funlukla elektronik muhafazalar i\u00e7in kullan\u0131l\u0131r).<\/p>\n

Plastiklerin en temel fizikokimyasal \u00f6zellikleri re\u00e7inenin do\u011fas\u0131 taraf\u0131ndan belirlenir. Re\u00e7ineler, sentetik re\u00e7ineler olarak da bilinen do\u011fal ve insan yap\u0131m\u0131 re\u00e7ineler olarak s\u0131n\u0131fland\u0131r\u0131labilir.<\/p>\n

Re\u00e7inelerin hepsi polimerdir ve bu polimerler benzersiz bir i\u00e7 molek\u00fcler yap\u0131ya ve bir d\u0131\u015f molek\u00fcler yap\u0131ya sahiptir.<\/p>\n

Bir polimerin i\u00e7 yap\u0131s\u0131, polimerin en temel fizikokimyasal \u00f6zelliklerini belirler. Polimerin d\u0131\u015f yap\u0131s\u0131 ise i\u015fleme \u00f6zelliklerini ve polimerin fiziksel ve mekanik \u00f6zelliklerini belirler.<\/p>\n

PCTFE \u0131s\u0131ya kar\u015f\u0131 daha hassast\u0131r ve y\u00fcksek s\u0131cakl\u0131klarda kolayca ayr\u0131\u015f\u0131r. Poliviniliden flor\u00fcr (PVDF), beyaz toz halinde, kristal termoplastik bir re\u00e7inedir.<\/p>\n

(8) Sel\u00fclozik plastikler<\/strong>
Sel\u00fclozik plastikler, do\u011fal sel\u00fcloz ve inorganik veya organik asitler art\u0131 plastikle\u015ftiricilerin etkisiyle \u00fcretilen sel\u00fcloz re\u00e7inelerinden yap\u0131l\u0131r. Sel\u00fcloz en eski yar\u0131 sentetik termoplastiktir.<\/p>\n

Yayg\u0131n olarak kullan\u0131lan sel\u00fcloz nitrat sel\u00fcloz asetat, sel\u00fcloz asetat b\u00fctiratt\u0131r ve enjeksiyon kal\u0131plama malzemesi i\u00e7in sel\u00fcloz asetat ana malzemedir.<\/p>\n

(9) Y\u00fcksek s\u0131cakl\u0131\u011fa dayan\u0131kl\u0131 re\u00e7ineler<\/strong>
Bunlar polis\u00fclfon, poliaril s\u00fclfon, polifenilen eter s\u00fclfon, polifenilen s\u00fclf\u00fcr, polifenilen eter, poliimiddir. Bu polimerler, molek\u00fcl\u00fcn ana zincirinde arilen gruplar\u0131 veya heterosiklik yap\u0131lar i\u00e7erir, bu nedenle y\u00fcksek s\u0131cakl\u0131k direncine, radyasyon direncine ve her ikisine de sahiptirler.<\/p>\n

Radyasyona kar\u015f\u0131 dayan\u0131kl\u0131d\u0131rlar ve y\u00fcksek darbe dayan\u0131m\u0131na ve boyutsal kararl\u0131l\u0131\u011fa sahiptirler.<\/p>\n

Polis\u00fclfon (PSF), bisfenol A polis\u00fclfon, bi\u00e7imsel bir yap\u0131ya sahip olan ancak amorf bir yap\u0131sal formda kalan do\u011frusal bir termoplastik polimerdir. Polis\u00fclfon daha y\u00fcksek bir viskoziteye sahiptir ve kesme h\u0131z\u0131ndan \u00e7ok s\u0131cakl\u0131\u011fa ba\u011fl\u0131d\u0131r.<\/p>\n

This is in contrast to polyethylene, which is similar to polycarbonate. In plastic injection molding service, when the shear rate is low, the effect of temperature on the swelling effect is not significant.<\/p>\n

Molek\u00fcler yap\u0131s\u0131nda alifatik gruplar i\u00e7ermeyen polifenilen eter s\u00fclfon (PES), \u0131s\u0131 direnci ve oksijen direnci a\u00e7\u0131s\u0131ndan daha iyidir. 180~200 derece aral\u0131\u011f\u0131nda uzun s\u00fcre kullan\u0131labilir ve erime s\u0131cakl\u0131\u011f\u0131 50~350 derecedir.<\/p>\n

Polifenilen eter (PPO), PPO ve di\u011fer bir\u00e7ok termoplastik farkl\u0131d\u0131r; eriyi\u011fin reolojik \u00f6zellikleri Newtonian bir s\u0131v\u0131n\u0131nkine yak\u0131nd\u0131r ve viskozite kesme h\u0131z\u0131na \u00f6nemli \u00f6l\u00e7\u00fcde ba\u011fl\u0131 de\u011fildir. Enjeksiyon kal\u0131plama i\u00e7in ayr\u0131ca modifiye polifenilen eterler ve klorlu polieterler de kullan\u0131l\u0131r.<\/p>\n

M\u00fckemmel genel performansa sahip yeni bir m\u00fchendislik plasti\u011fi t\u00fcr\u00fc olan polifenilen s\u00fclfit (PPS, Retten), \u015fu anda muylular ve rulmanlar i\u00e7in en iyi k\u00f6y malzemesidir.<\/p>\n

Do\u011frudan i\u015fleme zorluklar\u0131 bu nedenle ak\u0131\u015fkanl\u0131\u011f\u0131 art\u0131rmak i\u00e7in \u00e7apraz ba\u011fl\u0131 \u00f6n i\u015flem yap\u0131lmal\u0131d\u0131r. PSS'nin plastik enjeksiyon kal\u0131plama malzemesi HDPE'ye \u00e7ok benzer, ancak fark PSS'nin daha y\u00fcksek bir kal\u0131plama gerektirmesidir. S\u0131cakl\u0131k daha y\u00fcksektir: bu 343 derecede ak\u0131\u015fkanl\u0131k HDPE'ninkine e\u015fde\u011ferdir.<\/p>\n

Termoplastik Kau\u00e7uk (TPR), di\u011fer bir deyi\u015fle elastomer, ba\u015fka bir enjeksiyon kal\u0131plama malzemesidir. Plastik par\u00e7alar ve kau\u00e7uk kar\u0131\u015f\u0131m\u0131 i\u00e7erir. Teller ve kablo yal\u0131t\u0131m\u0131 gibi otomotiv par\u00e7alar\u0131 ve ev aletleri gibi di\u011fer uygulamalar i\u00e7in kullan\u0131l\u0131r.<\/p>\n

Termoplastik Poli\u00fcretan (TPU) TPU elastikiyet, \u015feffafl\u0131k ve diren\u00e7 gibi bir\u00e7ok farkl\u0131 \u00f6zelli\u011fe sahiptir. \u00d6zellikleri yumu\u015fak ve sert segmentleridir. Bu plastik t\u00fcr\u00fcn\u00fcn ana kullan\u0131m alan\u0131 cep telefonlar\u0131 i\u00e7in k\u0131l\u0131flar\u0131n yan\u0131 s\u0131ra klavye koruyucular\u0131 ve ayakkab\u0131lard\u0131r.<\/p>\n
