Nhoroondo yeSilicone additives / Silicone masterbatch/ Siloxane masterbatchuye kuti inoshanda sei mukatiwaya & tambo zvinosanganiswaindasitiri?
Silicone additives pamwe50% inoshanda silicone polymeryakapararira mukutakura senge polyolefin kana mineral, ine chimiro chegranular kana poda, inoshandiswa zvakanyanya seyamuro yekugadzirisa muwaya & tambo indasitiri. Zvigadzirwa zvinozivikanwa zvakadaiSILOXANE MB50nhepfenyuro inoshanda semafuta kana rheological modifier muwaya & tambo indasitiri uye yakatanga kuunzwa kubva kuDow Corning muUnited States makore makumi maviri apfuura, kozotiimwe SILICONE MASTERBATCH MB50akaonekwa pamusika na70% inoshanda silicone polymerakaparadzirwa mutakuri se silica, aine chimiro chegranular zvakare, ipapo zvigadzirwa kubva kuChengdu Silike zvakaonekwa pamusika kubva gore ra2004, ine silicone yemukati kubva 30-70% uye granular kana hupfu fomu.
Iyo tekinoroji paramita yekutengeserana silicone masterbatch inofanira kusanganisira zvinotevera zvirimo:
(1) Kana ukashanda semafuta kana rheological modifier, zvirimo zvinobva pa5 kusvika 50%
(2) Mutakuri anofanirwa kuenderana nesilicone uye mushandisi mukuru fomula substrate inofanirwa kutariswa, ine zita repolymer chiratidzo uye kunyungudutsa indekisi yemutakuri, kuitira kuti vashandisi vataure pairi pakugadzira fomula. Kana inorganic mineral powder inoshandiswa semutakuri, zita rehupfu rinofanira kuratidzwa. Huchena uye hunyoro hwehupfu hwakakosha kune vatengi, uye chena uye micron saizi poda inofanirwa kusarudzwa zvakanyanya sezvinobvira kugadzirwa.
Pakushanda semafuta kana rheological modifiers
Nezve polyethylene zvinhu
Sezvinozivikanwa, chiitiko che "shark ganda" chinowanzoitika kana extruding polyethylene insulated kana sheathed waya uye tambo, kunyanya kana extruding linear yakaderera density polyethylene (LLDPE) kana Ultra-yakaderera density polyethylene (ULDPE kana POE). Extruded cross-linked polyethylene materials (ingave peroxide cross-linking kana silane cross-linking) dzimwe nguva inosangana ne "shark skin" chiitiko, nekuda kwekusatariswa kwakakwana kwegadziriro yekuzora muhuwandu hwezvinhu. Ikozvino tsika yepasirese ndeyekuwedzera kuteedzera huwandu hwefluoropolymers kune fomula, asi mutengo wakakwirisa uye mashandisirwo ane mashoma.
Nehushoma hweUltra-yakakwirira molecular uremu silicone(0.1-0.2%) kune polyethylene kana muchinjika-yakabatana polyethylene inogona kudzivirira zvinobudirira chizvarwa che "shark ganda". Panguva imwecheteyo, ine lubrication mhedzisiro, inogona kunyatso kudzikisa extrusion torque kudzivirira iyo inodhonza mota kuti isamire nekuda kwekuremerwa.
Silicone inoshandiswa semafuta, nekuda kwekuwedzera kwayo kushoma, inofanirwa kugoverwa zvakaenzana muzvinyorwa kuitira kuti ishande panguva yekugadziriswa. Nekuda kwekemikari inertness yesilicone, haizoite makemikari nezvikamu zviri mufomu. Zvinokurudzirwa kuti fekitori yemidziyo yetambo yakaenzana isanganise silicone muplasticizing granulation process kufambisa kushandiswa kwetambo fekitori.
ForHalogen yemahara murazvo retardent (HFFR) tambo macomputer
Pamusana pekuvapo kwehuwandu hwakawanda hwemoto retardants (mineral powder) muHFFR cable compounds, izvo zvinoguma nehupamhi hwepamusoro uye husina kunaka hwekuyerera panguva yekugadzirisa; Iyo yakakwira viscosity inoita kuti zviome kuti mota idhonze panguva yeextrusion, uye iyo yakashata fluidity inoguma mune shoma shoma yeglue inogadzirwa panguva yeextrusion. Saka, kana fekitori yetambo ichiburitsa halogen-isina tambo, kugona kunongova 1/2-1/3 ye polyvinyl chloride tambo.
Nehumwe huwandu hwesilicone mune fomula, kwete chete kugadzirisa senge kuyerera kwakagadziridzwa asi zvakare kuwana zvirinani murazvo wemoto wezvinhu.
