Silicone zvinowedzera zvine50% silicone polymer inoshandayakapararira mukutakura senge polyolefin kana mineral, ine chimiro chegranular kana upfu, inoshandiswa zvakanyanya senzira dzekugadzirisa muindasitiri yewaya netambo. Zvigadzirwa zvinozivikanwa sengeSILOXANE MB50nhevedzano inoshanda semafuta kana kuti rheological modifier muindasitiri yewaya netambo uye yakatanga kuunzwa kubva kuDow Corning muUnited States makore makumi maviri apfuura, ndokuzoteveraimwe nzira yeSILICONE MASTERBATCH MB50akaonekwa pamusika aine70% silicone polymer inoshandaZvakaparadzirwa muchinhu chinotakura senge silica, zvine chimiro chegranular zvakare, zvigadzirwa zveChengdu Silike zvakazoonekwa pamusika kubva mugore ra2004, zvine silicone kubva pa30-70% uye granular kana upfu.

Magadzirirwo ehunyanzvi e silicone masterbatch yekutengeserana anofanirwa kusanganisira zvinotevera:

(1) Kana ichishanda semafuta kana rheological modifier, zvirimo zvinobva pa5 kusvika 50%.

(2) Muchina wekutakura unofanirwa kuenderana nesilicone uye substrate huru yemushandisi inofanira kufungwa nezvayo, ine chiratidzo chezita repolymer uye index yekunyunguduka yemuchina wekutakura, kuitira kuti vashandisi vagone kuishandisa pavanenge vachigadzira fomura. Kana upfu hwemineral husina kugadzirwa huchishandiswa semuchina wekutakura, zita reupfu rinofanira kuratidzwa. Kuchena uye kupfava kweupfu husina kugadzirwa kwakakosha kune vatengi, uye upfu huchena nehukuru hwe micron hunofanira kusarudzwa zvakanyanya sezvinobvira pakugadzirwa.

Pakushanda semafuta kana rheological modifiers

Zvezvinhu zvePolyethylene

Sezvazvinozivikanwa, chiitiko che "ganda reshark" chinowanzoitika kana uchiburitsa waya netambo dzakaputirwa nepolyethylene, kunyanya kana uchiburitsa linear low-density polyethylene (LLDPE) kana ultra-low density polyethylene (ULDPE kana POE). Zvinhu zve polyethylene zvakaburitswa (ingava peroxide cross-linking kana silane cross-linking) dzimwe nguva zvinosanganawo nechiitiko che "ganda reshark", nekuda kwekusanyatsoongorora sisitimu yemafuta mufomura yezvinhu. Maitiro aripo pasi rose ndeekuwedzera huwandu hwe fluoropolymers mufomura, asi mutengo wacho wakakwira uye kushandiswa kwacho kwakaganhurirwa.

Nehuwandu hushoma hwesilicone inorema zvakanyanya-yakakwira(0.1-0.2%) ku polyethylene kana polyethylene yakabatana inogona kudzivirira kugadzirwa kwe "shark skin". Panguva imwe chete, nekushanda kwayo kwekunyorovesa, inogona kuderedza torque ye extrusion kudzivirira mota inodhonza kuti isamire nekuda kwekuwanda kwemafuta.

Silicone inoshandiswa semafuta, nekuda kwekuwedzera kwayo kushoma, inofanira kugoverwa zvakaenzana muzvinhu izvi kuitira kuti ishande panguva yekugadzirisa. Nekuda kwekusashanda kwemakemikari kwesilicone, haizosanganisike nemakemikari nezvinhu zviri mufomura. Zvinokurudzirwa kuti fekitori yezvinhu zvetambo isanganise silicone zvakaenzana mupurasitiki kuti ive nyore kushandisa fekitori yetambo.

ZveMakerubhi eHalogen asina murazvo anodzora moto (HFFR) 

Nekuda kwekuvapo kwehuwandu hwakawanda hwezvinodzivisa moto (mineral powder) muHFFR cable compounds, izvo zvinokonzera viscosity yakanyanya uye kutadza kufamba zvakanaka panguva yekugadzirisa; viscosity yakanyanya inoita kuti mota isakwanise kudhonza panguva yekuburitsa, uye fluidity shoma inoguma neglue shoma inogadzirwa panguva yekuburitsa. Saka, kana fekitori yetambo ichiburitsa tambo dzisina halogen, kushanda zvakanaka kunongova 1/2-1/3 yetambo yepolyvinyl chloride.

Kana paine huwandu hwakati hwesilicone mufomura, hazvingori nyore chete kugadzirisa zvinhu zvakaita sekuyerera kwemvura asiwo zvinoita kuti moto usanyanya kudzima.
