Amateka yaInyongera ya Silicone / Igishushanyo cya Silicone / Igishushanyo cya Siloxanenuburyo ikorainsinga & insingainganda?

Silicone yongeyeho50% ikora silicone polymerikwirakwizwa mubitwara nka polyolefine cyangwa minerval, hamwe nuburyo bwa granular cyangwa ifu, bikoreshwa cyane nkibikoresho byo gutunganya inganda ninsinga. Ibicuruzwa bizwi nkaSILOXANE MB50Urukurikirane rukora nka lubricant cyangwa rheological modifier munganda za wire & kabili kandi byatangijwe bwa mbere kuva Dow Corning muri Amerika hashize imyaka makumyabiri, hanyumaubundi SILICONE MASTERBATCH MB50yagaragaye ku isoko hamwe70% ikora silicone polymeryatatanye mu bwikorezi nka silika, hamwe na granular nayo, hanyuma ibicuruzwa biva muri Chengdu Silike byagaragaye ku isoko guhera mu mwaka wa 2004, birimo silicone kuva 30-70% hamwe na granular cyangwa ifu.

Ibikoresho bya tekinike yubucuruzi bwa silicone masterbatch igomba kuba ikubiyemo ibintu bikurikira:

(1) Iyo ukora nka lubricant cyangwa rheological modifier, ibirimo biri hagati ya 5 na 50%

. Niba ifu yumutungo kamere idakoreshwa nkuwitwaye, izina ryifu rigomba kwerekanwa. Umweru nubwiza bwifu ya organic organique ningirakamaro kubakiriya, kandi ifu yera na micron nini igomba guhitamo ibishoboka byose kugirango ikorwe.

Iyo ukora nk'amavuta cyangwa abahindura imvugo

Kubikoresho bya Polyethylene

Nkuko bizwi, ikibazo cy "uruhu rwa shark" gikunze kugaragara mugihe cyo gukuramo polyethylene ikingiwe cyangwa yometseho insinga ninsinga, cyane cyane iyo ikuramo umurongo muto wa polyethylene (LLDPE) cyangwa polyethylene (ULDPE cyangwa POE). Ibikoresho bisohotse byahujwe na polyethylene (yaba peroxide ihuza cyangwa silane ihuza) nayo rimwe na rimwe ihura nibintu byitwa "uruhu rwa shark", bitewe no gutekereza ku buryo budahagije bwo gusiga amavuta muri formulaire y'ibikoresho. Imyitozo mpuzamahanga iriho ubu ni ukongera umubare wa fluoropolymers kuri formula, ariko ikiguzi ni kinini kandi gusaba ni bike.

Hamwe na bikeultra-high molecular silicone(0.1-0.2%) kuri polyethylene cyangwa polyethylene ihujwe irashobora gukumira neza kubyara "uruhu rwa shark". Muri icyo gihe, hamwe ningaruka zayo zo gusiga, irashobora kugabanya neza itara ryo gukuramo kugirango irinde moteri ikurura guhagarara kubera kurenza urugero.

Silicone ikoreshwa nk'amavuta, kubera kwiyongera kwayo, igomba gukwirakwizwa mu bikoresho kugira ngo ikore mu gihe cyo kuyitunganya. Bitewe nubusembwa bwa chimique ya silicone, ntabwo izakora imiti hamwe nibigize muri formula. Birasabwa ko uruganda rukora ibikoresho rwa kabili ruvanga silicone muburyo bwo guhindagura plastike kugirango byorohereze ikoreshwa ryuruganda.

KuriHalogen yubusa flame retardent (HFFR) insinga ya kabili 

Bitewe no kuba hari umubare munini wa retardants ya flame (minerval yifu) mumashanyarazi ya HFFR, bivamo ubukonje bwinshi kandi bitagenda neza mugihe cyo gutunganya; Ubukonje bwinshi butuma bigora moteri gukurura mugihe cyo kuyisohora, kandi amazi mabi atera glue nkeya yakozwe mugihe cyo kuyisohora. Rero, iyo uruganda rwumugozi rusohora insinga zidafite halogene, imikorere ni 1 / 2-1 / 3 gusa ya kabili ya polyvinyl chloride.

Hamwe numubare runaka wa silicone muri formula, ntabwo itunganywa gusa nkuko bigenda neza ariko nanone ikabona umuriro mwiza wo kubika ibikoresho.
