Ulwelo lweTin Unyango lweSilicone Urethane kuBugcisa boBuchule bokuMngunda

inkcazelo emfutshane:

I-silicone yokungunda kwamanzi inobomi beshelufu yeenyanga ezili-12.

Ulwelo lokungunda ijeli ye-silica yijeli ye-silica enamacandelo amabini.Ngokuqhelekileyo igcinwa kwindawo engenamoya, epholileyo, neyomileyo, ivalwe kwaye igcinwe kude nabantwana kwaye kude nelanga elithe ngqo.Ngexesha lokuthutha, iglu A kunye neglu B ayinakuxutywa ngokulinganayo ngaphambi kokuba igcinwe.Oku kuya kubangela ukuba yonke ijeli ye-silicone iqine kwaye iholele ekukhutsheni.

Iithegi zeMveliso

Ubunzima be-silicone obuhlukeneyo bunoluhlu oluhlukeneyo lwesicelo

0 Shore A kunye 0 Shore 30C ubulukhuni.Olu hlobo lwe-silicone luthambile kakhulu kwaye lune-Q-elasticity elungileyo.Ihlala isetyenziselwa ukwenza iimveliso ezigqityiweyo ezilinganisa iindawo ezithile zomzimba womntu, ezifana neepads zesifuba, iipads zamagxa, ii-insoles, njl.

5 ~ 10 ubulukhuni.Kufanelekile ukuzalisa kunye nokuphequlula imodeli yeemveliso kunye neepatheni ezintle kakhulu kunye nokuchithwa okulula, njengokuveliswa kwe-silicone molds yeesepha kunye namakhandlela.

20 degrees ubulukhuni.Kufanelekile ukwenza imisebenzi yezandla ezincinci.Ine-viscosity ephantsi, ukuguquguquka okuhle, ukusebenza ngokulula, ukukhupha amaqamza ngokulula, ukunyameka okulungileyo kunye namandla akralayo, kunye nokugalela lula.

40 degrees ubulukhuni.Kwiimveliso ezinkulu, ine-viscosity ephantsi, i-fluidity elungileyo, ukusebenza lula, ukukhulula amaqamza ngokulula, ukunyameka okulungileyo kunye namandla okukrazula, kunye nokuzaliswa lula.

Ukuba usebenzisa inkqubo yokubumba ibrashi ye-multi-layer, unokukhetha i-silicone yobunzima obuphezulu, njenge-30A okanye i-35A, ekulula ukuyisebenzisa kwaye akukho lula ukuyiphazamisa.

Iimbonakalo

Series rubbers ziqulathe ulwelo Icandelo B isiseko kunye Part A accelerator, nto leyo emva kokuxubana ngokomlinganiselo ofanelekileyo ngokobunzima, ukunyanga kwiqondo lobushushu eliguquguqukayo, amandla aphezulu iinyembezi, RTV (igumbi lobushushu vulcanizing) abicah rubbers.Zilungele ukubumba apho ukukhululwa ngokulula okanye ukumelana nobushushu obuphezulu kuyafuneka.Zinconywa nge-polyurethane, i-polyester, i-epoxy resins, kunye ne-wax.

Irabha ye-Silicone isetyenziswa rhoqo xa kusenziwa iintlaka zeplastiki ezingamanzi, ezinje nge-polyurethane, i-epoxy okanye i-polyester kuba iintlaka okanye iidyasi zomqobo ezisetyenziswa kunye nazo azifuni arhente yokukhulula.Ngaloo ndlela, iinxalenye zeplastiki ezivela kwi-silicone molds zihlala zilungele ukugqiba ngaphandle kokuhlamba ukukhutshwa okanye ukungafezeki kwendawo ngenxa yokukhupha ii-agent.

Iimold zeSilicone zikwamelana namaqondo obushushu aphezulu (+ 250°F) wepolyester okanye i-acrylic resins okanye iintsimbi ezinyibilikayo ezisezantsi ngcono kunayo nayiphi na enye irabha.
