Mbiri yaZowonjezera za Silicone / Silicone masterbatch/ Siloxane masterbatchndi momwe zimagwirira ntchitowaya & chingwe mankhwalamakampani?

Zowonjezera za silicone ndi50% ntchito silikoni polimaomwazika chonyamulira ngati polyolefin kapena mchere, ndi mawonekedwe a granular kapena ufa, chimagwiritsidwa ntchito ngati zothandizira kukonza mu waya & chingwe makampani. Odziwika mankhwala ngatiSILOXANE MB50mndandanda umagwira ntchito ngati lubricant kapena rheological modifier mumakampani a waya & chingwe ndipo idayambitsidwa koyamba kuchokera ku Dow Corning ku United States zaka makumi awiri zapitazo, kenakonjira ina SILICONE MASTERBATCH MB50adawonekera pamsika ndi70% ntchito silikoni polimaomwazika chonyamulira ngati silika, ndi mawonekedwe a granular komanso, kenako zinthu zochokera ku Chengdu Silike zidawonekera pamsika kuyambira mchaka cha 2004, zokhala ndi silikoni kuchokera 30-70% ndi mawonekedwe a granular kapena ufa.

Magawo aukadaulo amalonda a silicone masterbatch ayenera kukhala ndi izi:

(1) Mukamagwira ntchito ngati mafuta kapena rheological modifier, zomwe zili pakati pa 5 mpaka 50%

(2) Chonyamuliracho chiyenera kukhala chogwirizana ndi silikoni ndipo gawo lalikulu la wogwiritsa ntchito liyenera kuganiziridwa, ndi chizindikiro cha dzina la polima ndi ndondomeko yosungunuka ya chonyamulira, kuti ogwiritsa ntchito azitha kutchulapo popanga chilinganizo. Ngati inorganic mineral powder imagwiritsidwa ntchito ngati chonyamulira, dzina la ufa liyenera kuwonetsedwa. Kuyera ndi kufinya kwa ufa wa inorganic ndikofunikira kwa makasitomala, ndipo ufa woyera ndi wa micron uyenera kusankhidwa momwe ungathere kuti upangidwe.

Pamene ntchito monga lubricant kapena rheological modifiers

Kwa polyethylene zinthu

Monga amadziwika, chodabwitsa cha "shaki khungu" nthawi zambiri zimachitika pamene extruding polyethylene insulated kapena mawaya sheathed ndi zingwe, makamaka extruding liniya otsika osalimba polyethylene (LLDPE) kapena kopitilira muyeso-otsika osalimba polyethylene (ULDPE kapena POE). Zida za polyethylene zowonjezera zowonjezera (kaya zogwirizanitsa ndi peroxide kapena kugwirizanitsa silane) nthawi zina zimakhala ndi zochitika za "khungu la shark", chifukwa chosaganizira bwino za dongosolo lopaka mafuta muzinthu zakuthupi. Mchitidwe wapadziko lonse lapansi pano ndikuwonjezera kuchuluka kwa ma fluoropolymers ku formula, koma mtengo wake ndi wokwera ndipo kugwiritsa ntchito kwake kuli kochepa.

Ndi pang'ono pang'onoultra-high molecular kulemera silikoni(0.1-0.2%) ku polyethylene kapena polyethylene yolumikizana ndi mtanda imatha kuteteza m'badwo wa "khungu la shark". Nthawi yomweyo, ndi mphamvu yake yothira mafuta, imatha kuchepetsa mphamvu ya extrusion kuti iteteze mota yokoka kuyimitsa chifukwa chakuchulukirachulukira.

Silicone yogwiritsidwa ntchito ngati mafuta, chifukwa chowonjezera pang'ono, iyenera kugawidwa mofanana muzinthuzo kuti igwire ntchito panthawi yokonza. Chifukwa cha inertness yamankhwala a silikoni, sichingafanane ndi mankhwala ndi zigawo zomwe zili mu ndondomekoyi. Ndibwino kuti chingwe fakitale chuma wogawana kusakaniza silikoni mu ndondomeko plasticizing granulation kuti atsogolere ntchito fakitale chingwe.

ZaHalogen free flame retardent (HFFR) chingwe chophatikizira 

Chifukwa cha kukhalapo kwa mafuta ambiri oletsa moto (mineral powder) muzitsulo za chingwe cha HFFR, zomwe zimabweretsa kukhuthala kwakukulu komanso kusayenda bwino panthawi yokonza; Kukhuthala kwapamwamba kumapangitsa kuti pakhale zovuta kuti galimotoyo ikoke panthawi ya extrusion, ndipo kuchepa kwamadzimadzi kumabweretsa kagulu kakang'ono kagulu kamene kamapangidwa panthawi ya extrusion. Chifukwa chake, fakitale ya chingwe ikatulutsa zingwe zopanda halogen, mphamvu yake ndi 1/2-1/3 ya chingwe cha polyvinyl chloride.

Ndi kuchuluka kwa silikoni mu chilinganizo, osati processing monga flowability bwino komanso kupeza bwino lawi retardancy kwa zakuthupi.
