Umlando weIzithasiselo ze-silicone / i-Silicone masterbatch/ i-Siloxane masterbatchnokuthi isebenza kanjani kuizinhlanganisela zentambo nekhebulaimboni?

Izithasiselo ze-silicone ezine-I-polymer ye-silicone esebenzayo engu-50%isakazeke ku-carrier efana ne-polyolefin noma i-mineral, enohlobo lwe-granular noma i-powder, esetshenziswa kabanzi njengezinsiza zokucubungula embonini yezintambo nezintambo. Imikhiqizo eyaziwayo efanaI-SILOXANE MB50umsebenzi wochungechunge njengomuthi wokugcoba noma wokuguqula amathambo embonini yezintambo nezintambo futhi wethulwa okokuqala eDow Corning e-United States eminyakeni engamashumi amabili edlule, kwabe sekuba yi-enye i-SILICONE MASTERBATCH MB50kuvele emakethe ngeI-polymer ye-silicone esebenzayo engu-70%Isakazeke ku-carrier efana ne-silica, kanye nohlobo lwe-granular, kwabe sekubonakala imikhiqizo evela eChengdu Silike emakethe kusukela ngonyaka ka-2004, enokuqukethwe kwe-silicone kusuka ku-30-70% kanye nohlobo lwe-granular noma lwe-powder.

Amapharamitha obuchwepheshe e-masterbatch ye-silicone yezentengiselwano kufanele afake okuqukethwe okulandelayo:

(1) Uma usebenza njengomuthi wokugcoba noma wokuguqula amalunga omzimba, okuqukethwe kusuka ku-5 kuya ku-50%

(2) Isithwali kufanele sihambisane ne-silicone futhi kufanele kucatshangelwe i-substrate yefomula eyinhloko yomsebenzisi, kanye nenkomba yegama le-polymer kanye nenkomba yokuncibilika yesithwali, ukuze abasebenzisi bakwazi ukubhekisela kuyo lapho beklama ifomula. Uma kusetshenziswa i-powder yamaminerali engaphili njengesithwali, igama le-powder kufanele liboniswe. Ubumhlophe kanye nobukhulu be-powders engaphili kubalulekile kumakhasimende, futhi i-powders emhlophe nesayizi ye-micron kufanele ikhethwe ngangokunokwenzeka ukuze ikhiqizwe.

Uma usebenza njengezithambisi noma izilungisi ze-rheological

Kwezinto ze-Polyethylene

Njengoba kwaziwa kahle, isimo "sesikhumba sikashaka" sivame ukwenzeka lapho kukhishwa izintambo nezintambo ze-polyethylene ezifakwe uthayela noma ezifakwe isivikelo, ikakhulukazi lapho kukhishwa i-polyethylene eqondile enesisindo esiphansi (LLDPE) noma i-polyethylene ephansi kakhulu (ULDPE noma i-POE). Izinto ze-polyethylene ezixhunywe nge-cross-linked (kungakhathaliseki ukuthi i-peroxide cross-linking noma i-silane cross-linking) nazo ngezinye izikhathi zithola isimo "sesikhumba sikashaka", ngenxa yokungacabangeli ngokwanele uhlelo lokugcoba kufomula yezinto ezibonakalayo. Umkhuba wamanje wamazwe ngamazwe ukwengeza amanani amancane e-fluoropolymers kufomula, kodwa izindleko ziphezulu futhi ukusetshenziswa kunqunyelwe.

Ngenani elincane lei-silicone enesisindo sama-molecule ephezulu kakhulu(0.1-0.2%) ku-polyethylene noma i-polyethylene exhumene nayo ingavimbela ngempumelelo ukukhiqizwa "kwesikhumba sikashaka". Ngesikhathi esifanayo, ngomphumela wayo wokugcoba, inganciphisa ngempumelelo i-torque yokukhipha ukuze ivimbele injini ehudulayo ukuthi ingami ngenxa yokugcwala ngokweqile.

I-silicone esetshenziswa njengesithambisi, ngenxa yokufakwa kwayo okuncane, kumele isatshalaliswe ngokulinganayo ezintweni ukuze isebenze ngesikhathi sokucubungula. Ngenxa yokungasebenzi kwamakhemikhali kwe-silicone, ngeke isabele ngamakhemikhali nezingxenye ezikule fomula. Kunconywa ukuthi ifektri yezinto zekhebula ixube i-silicone ngokulinganayo enqubweni yokuhlanganisa ipulasitiki ukuze kube lula ukusebenzisa ifektri yekhebula.

NgobaIzinhlanganisela zekhebula ezingenalo ilangabi elivimbela ilangabi (HFFR) 

Ngenxa yokuba khona kwenani elikhulu lezinto ezivimbela ilangabi (impuphu yamaminerali) kuma-compounds ekhebula le-HFFR, okubangela i-viscosity ephezulu kanye nokugeleza okubi ngesikhathi sokucubungula; i-viscosity ephezulu yenza kube nzima ukuthi injini idonse ngesikhathi sokukhipha, futhi ukugeleza okubi kuholela enanini elincane leglue elikhiqizwa ngesikhathi sokukhipha. Ngakho-ke, lapho ifektri yekhebula ikhipha izintambo ezingenayo i-halogen, ukusebenza kahle kungama-1/2-1/3 kuphela ekhebula le-polyvinyl chloride.

Uma inani elithile le-silicone lisefomini, akugcini nje ngokuthuthukiswa kokucutshungulwa njengokugeleza kwamanzi kodwa futhi kuthola nokuncipha komlilo okungcono kwezinto.
