Amateka yaInyongera za silicone / Silicone masterbatch / Siloxane masterbatchn'uko bikora muriinsinga n'insingainganda?

Inyongera za silikoni hamwe na50% polimeri ya silikoni ikora nezaikwirakwijwe mu cyuma gitwara ibintu nka polyolefin cyangwa amabuye y'agaciro, irimo ubwoko bwa granular cyangwa ifu, ikoreshwa cyane nk'ibikoresho bifasha mu gutunganya insinga n'insinga. Ibicuruzwa bizwi nkaSILOXANE MB50akazi ko gusiga amavuta cyangwa guhindura imikorere y'imitsi mu nganda z'insinga n'insinga, kandi katangiye gutangwa na Dow Corning muri Leta Zunze Ubumwe za Amerika mu myaka makumyabiri ishize, hanyumaubundi buryo bwa SILICONE MASTERBATCH MB50yagaragaye ku isoko hamwe na70% polimeri ya silikoni ikora nezaIbicuruzwa bya Chengdu Silike byakwirakwijwe mu buryo bwa silike, hamwe n’ubwoko bwa granular, hanyuma ibicuruzwa bya Chengdu Silike byagaragaye ku isoko kuva mu mwaka wa 2004, bifite silicone kuva kuri 30-70% n’ibice bya granular cyangwa ifu.

Ibipimo bya tekiniki bya silicone masterbatch y'ubucuruzi bigomba kuba bikubiyemo ibi bikurikira:

(1) Iyo ikoreshwa nk'amavuta yo kwisiga cyangwa guhindura imikorere y'imitsi, ibikubiye muri iyo mitsi biri hagati ya 5 na 50%

(2) Umuyoboro ugomba kuba uhuye na silicone kandi substrate y'ingenzi y'umukoresha igomba kwitabwaho, hamwe n'izina rya polymer n'ikimenyetso cyo gushonga cy'umuyoboro, kugira ngo abakoresha bashobore kubyifashisha mu gushushanya iyo formula. Niba ifu y'amabuye y'agaciro adafite umwimerere ikoreshwa nk'umuyoboro, izina ry'ifu rigomba kugaragazwa. Ubuziranenge n'ubuto bw'ifu y'umwimerere ni ingenzi ku bakiriya, kandi ifu y'umweru n'ingana na mikoroni igomba guhitamo uko bishoboka kose kugira ngo ikoreshwe.

Iyo ukoze nk'amavuta yo kwisiga cyangwa ubuvuzi bw'imitsi

Ku bikoresho bya polyethylene

Nkuko bizwi, ikintu kigaragara ku "ruhu rw'ishaka" gikunze kubaho iyo hasohotse insinga n'imigozi bya polyethylene birinda cyangwa bifite sheath, cyane cyane iyo hasohotse polyethylene ifite ubucucike buciriritse (LLDPE) cyangwa polyethylene ifite ubucucike bukabije (ULDPE cyangwa POE). Ibikoresho bya polyethylene bifite ubucucike bukabije (byaba peroxide cross-linking cyangwa silane cross-linking) nabyo rimwe na rimwe bihura n'ikibazo cya "uruhu rw'ishaka", bitewe no kudasuzuma neza sisitemu yo gusiga amavuta muri formula y'ibikoresho. Ubusanzwe ibikorwa mpuzamahanga ni ukongera ingano nto ya fluoropolymers muri formula, ariko igiciro ni kinini kandi ikoreshwa ni rike.

Hamwe n'ingano nto yasilicone ifite uburemere bwinshi cyane bwa molekile(0.1-0.2%) kuri polyethylene cyangwa polyethylene ifatanye bishobora gukumira kubyara "uruhu rw'ishaka". Muri icyo gihe, hamwe n'ingaruka zarwo zo kwisiga, bishobora kugabanya neza imbaraga zo gusohora kugira ngo hirindwe ko moteri ikurura idahagarara bitewe n'umutwaro mwinshi.

Silikoni ikoreshwa nk'amavuta yo kwisiga, bitewe nuko yongerwamo make, igomba gukwirakwizwa mu buryo bungana mu bikoresho kugira ngo ikore neza mu gihe cyo kuyitunganya. Kubera ko silikoni idakora neza mu buryo bwa shimi, ntabwo izakorana n'ibice biri muri formula. Ni byiza ko uruganda rw'ibikoresho by'insinga ruvanga silikoni mu buryo bungana mu buryo bwo kuyitera plastike kugira ngo byorohereze ikoreshwa ry'uruganda rw'insinga.

KuriInsinga zitagira umuriro wa Halogen (HFFR) 

Bitewe n’uko hari ingano nini y’ibintu bigabanya umuriro (ifu y’ubutare) mu byuma bya HFFR, bigatuma habaho ubushyuhe bwinshi no kutabasha gutembera neza mu gihe cyo gutunganya; ubushyuhe bwinshi butuma moteri igorana gukurura mu gihe cyo gusohora, kandi ubushyuhe buke butuma habaho kole nkeya mu gihe cyo gusohora. Rero, iyo uruganda rw’insinga rusohora insinga zidafite halogen, ubushobozi ni 1/2-1/3 gusa by’insinga za polyvinyl chloride.

Iyo ingano runaka ya silikoni iri muri formula, ntabwo gusa gutunganya nk'uko bigenda neza ahubwo binatuma umuriro udakora neza.
