Foam yeSilicone, inozivikanwawo sesilicone yakaumbwa, chigadzirwa cherabha chine maburi chakagadzirwa nerabha yesilicone sechinhu chepakutanga uye chinogadzirwa nefuro.

 

　　Nekuvandudzwa kuri kuramba kuchiitwa tekinoroji yefuro, asiwo nekuda kwehunhu hwayo hwepamusoro, nzvimbo dzekushandisa dziri kuwedzera kukura, dzakadai sezvisungo zvekuvhara, mapedhi ekudzivirira, magasket ekuvaka, zvinhu zvinodzivirira kutenderera, michina yekudzivirira nezvimwewo.

 

Nheyo ye silicone furo

 

　　Rubha resilicone rine furo, musimboti ndewekuwedzera furo mu silicone rabha compound yakasarudzwa, pasi pekumanikidzwa kwemamiriro ekupisa vulcanization silicone rabha foam, kuwedzera rabha kuti igadzire chimiro chebubble chakaita sesponge. Zvinhu zvikuru zvinosarudza uye zvinokanganisa chimiro chebubble huwandu hwegasi rinogadzirwa ne blowing agent, kumhanya kwegasi murabha, viscosity yerabha uye kumhanya kwe vulcanization. Kuti ugadzire zvigadzirwa zve silicone foam zviri nani, sarudzo yemhando dze foam agent uye rabha vulcanization system ndiyo kiyi.

 

　　Maitiro ekugadzira furo reSilicone

 

　　Foromo reSilicone rinofanira kupfuura nepakati pemaitiro ekugadzira, tekinoroji yekugadzirisa, chinongedzo chimwe nechimwe chichava nemhedzisiro paforomo resilicone rapera.

 

　　1, kuita purasitiki (ndiko kuti, kuita purasitiki kwerabha risina kucheneswa. Kureva kuti, hapana zvimwe zvinowedzerwa muchina wekuchenesa wakavhurika. Rega rabha inyorove kuti inyunguduke kuita chinhu chinoshanda pamwe chete (kugadzirira kusanganisa).

 

　　Chinangwa chikuru chekunatswa kwepurasitiki yerabha mbishi ndechekupwanya nekuparadza cheni yerabha yemacromolecular, kuvandudza plasticity yerabha, uye kuita kuti kusanganiswa nekusanganiswa kwemusanganiswa kuve nyore. Mukugadzirwa kwezvigadzirwa zverabha zvine furo, rabha mbishi inogadzirwa nepurasitiki zvizere, ichaita kuti plasticity yerabha ive nani, zvive nyore kuita kuti bubble buri rive rakafanana, low density, uye small shrinkage products.

 

2, kusanganisa, kureva kuti, rabha yepurasitiki yekuwedzera zvinhu zvakasiyana-siyana (zvekuwedzera) zvekunatsa.

 

Maitiro ekusanganisa zvinhu zvakasiyana-siyana zviri murabha isina kugadzirwa (kana kuti rabha inoisa purasitiki) mukuita kwekupararira kwakafanana. Sekusanganisa zvimwe zvinhu zvepolymer, kuti chinobatanidza chinhu chisanganiswe zvakaenzana murabha isina kugadzirwa, chinofanira kushandisa simba remuchina wekunatsa. Zvisinei, nekuti rabha ine zvikamu zvakawanda zvezvinoshanda pamwe chete, hunhu hwezvinoshanda pamwe chete hunosiyana zvikuru, uye pesvedzero yezvinoshanda pamwe chete pakuita kwekusanganisa, mwero wekupararira, uye chimiro cherabha ine kugadzirwa zvakanakawo, saka maitiro ekusanganisa rabha akaoma kupfuura mamwe mapolymer.

 

Maitiro ekusanganisa ane mhedzisiro yakakosha pakushanda kwezvinhu zverabha. Kusanganisa hakuna kunaka, rabha ichave isina kuenzana yekupararira kwe compatibilizer, plasticity yerabha yakanyanya kukwira kana kuderera, kupisa, chando nezvimwe zviitiko, izvo hazvingoiti chete kuti maitiro e calendering, pressing, molding uye vulcanization asagone kuitwa zvakajairika, asiwo zvinotungamira mukuderera kwekushanda kwechigadzirwa chapera, uye zvinogona kutokonzera kuti chigadzirwa chipere nekukurumidza. Saka, kusanganisa ndeimwe yemaitiro akakosha mukugadzirisa rabha.

 

　　3、Kupaka mota

 

　　Rabha iri mukusanganisa rapera, inofanira kuiswa kwenguva yakakodzera, kuitira kuti zvinhu zvakasiyana-siyana zvinowedzerwa mukusanganisa rabha zvakapararira zvakakwana, zvinhu zvinowedzerwa rabha zvakapararira zvakaenzana, kugadzikana kwehukuru hwechigadzirwa, mwero wekupfava kwepamusoro, mwero wekufanana kwemabhurumu zvakare zviri nani.

 

　　3、Tembiricha

 

　　Furo rerabha rinonzwa zvakanyanya tembiricha, rudzi rumwe chete rwerabha, mhedzisiro yefuro haina kufanana patembiricha dzakasiyana, nekuti sisitimu yefuro uye sisitimu yevulcanization inonzwa tembiricha yemadhigirii akasiyana, sisitimu inochinja, mwero wekufananidza wemusiyano, mhedzisiro yacho yakasiyanawo.

 

　　4, kuumba

 

　　Zvigadzirwa zverabha zvine furo zvinoteverwa nekugadzira uye nzira dzekuumba dzinotevera ndedzekuumba, kuumba, kuumba ndiro, nezvimwewo, zvichienderana nechimiro chinodiwa chechigadzirwa chapera, marongero, kureba, saizi, chimiro, kuomarara, ruvara rwakasiyana, pamwe nezvinodiwa zvemifananidzo, unogona kuita zvinhu zvisiri zvemhando yepamusoro.
