Silicone foam, inozivikanwawo seyakaumbwa silicone, ndeye porous rabha dhizaini chigadzirwa chakagadzirwa nesilicone rabha sechinhu chepasi uye chinogadzirwa nekupupa.

 

　　Nekuenderera mberi nekuvandudzwa kwehunyanzvi hwekupupuma furo, asi zvakare nekuda kwehunhu hwayo hwepamusoro, nzvimbo dzekushandisa dziri kuwedzera uye kuwanda, senge mitsetse yekuisa chisimbiso, mapedhi ekumisa, magasi ekuvaka, vibration yekuzviparadzanisa nevamwe, midziyo yekudzivirira uye zvichingodaro.

 

Nheyo yesilicone foam

 

　　Inopupuma silicone rabha, musimboti wekuwedzera furo mune yakasarudzwa silicone rabha kombi, pasi pekumanikidza kudziya vulcanization silicone rubber furo, kuwedzera rabha kuumba chipanje-sebubble chimiro. Zvinhu zvikuru zvinotarisisa nekupesvedzera chimiro chebubble kuwanda kwegasi rinogadzirwa neanofuridza, kukurumidza kwekupararira kwegasi murabha, viscosity yerabha uye kumhanya kwevulcanization. Kugadzira zvirinani silicone foam zvigadzirwa, kusarudzwa kweanopupa ejenti mhando uye rabha vulcanization system ndiyo kiyi.

 

　　Silicone foam yekugadzira maitiro

 

　　Silicone foam inoda kuenda kuburikidza neyakatevedzana yekugadzira maitiro, kugadzirisa tekinoroji, imwe neimwe link ichave nemhedzisiro pane yakapedzwa silicone foam.

 

　　1, plasticizing (ndiko kuti, plasticity yekunatsa rabha. Ndiko kuti, hapana zvekuwedzera mumuchina wekunatsa wakavhurika. Rega rabha ripfave kuti rinyunguduke mumubatanidzwa unoshanda (kugadzirira kusanganisa).

 

　　Izvo zvakakosha zvekunatswa kwepurasitiki yerabha mbishi kutyora nekuparadza macromolecular cheni yerabha, kuvandudza plastiki yerabha, uye kuita kuti kusanganisa uye kusanganisa kwekomboni kuve nyore. Mukugadzirwa kwezvigadzirwa zverabha zvine furo, raw rabha rakazara plasticized, rinoita kuti rabha plasticity ive nani, nyore kugadzira gomba rebubble kufanana, kuderera kwehudhi, zvigadzirwa zvidiki zvinodzikira.

 

2, kusanganisa, ndiko kuti, iyo plasticized rabha kuti uwedzere akasiyana-siyana maajenti (zvinowedzerwa) ekunatsa.

 

Kusanganisa maitiro akasiyana evamiririri mune raw rabha (kana plasticizing rabha) mukuita kwekupararira kweyunifomu. Sekusanganiswa kwezvimwe zvinhu zvepolymer, kuitira kuti compatibilizer ifanane yakasanganiswa murabha yakaomeswa, inofanirwa kushandisa yakasimba mechanical chiito yemuchina wekunatsa. Nekudaro, nekuti musanganiswa werabha une zvimwe zvikamu zveanoshandira pamwe, iyo morphological maitiro evanoshandira pamwe inosiyana zvakanyanya, uye pesvedzero yevashandi vanoshandira pamwe pakusanganiswa, dhigirii rekupararira, uye chimiro chekomboni yerabha zvakare yakakura kwazvo. saka kusanganiswa kwerabha kunenge kwakaoma kupfuura yezvimwe zvinhu zvepolymer.

 

Iko kusanganiswa kwemaitiro kune zvakakosha zvikuru pakushanda kwezvinhu zverubha. Kusanganisa hakuna kunaka, iyo rabha ichave isina kuenzana kupararira kwecompatibilizer, plasticity yerabha yakakwira zvakanyanya kana yakaderera, kupisa, chando uye zvimwe zviitiko, izvo zvisingazoiti chete calendering, kudzvanya, kuumba uye vulcanization process haigone kutakurwa. kunze zvakajairwa, asi zvakare zvinotungamira mukuita kwekuparara kwechigadzirwa chakapedzwa, uye zvinogona kutokonzera chigadzirwa chekutanga kwehupenyu. Naizvozvo, kusanganisa ndeimwe yenzira dzakakosha mukugadzira rubber.

 

　　3,Parking

 

　　Rubber mukusanganiswa inopedzwa, inofanira kuiswa kwenguva yakakodzera, kuitira kuti zvakasiyana-siyana zvekuwedzera mukusanganiswa kwerabha zvakaparadzirwa zvizere, rubber additives akaparadzirwa zvakaenzana, kugadzikana kwehukuru hwechigadzirwa, chiyero chekutsetseka kwechigadzirwa. pamusoro, dhigirii yekufanana kwemabhubhu zvakare iri nani.

 

　　3,Tembiricha

 

　　Rubber furo rinonyanya kutarisisa tembiricha, iyo yakafanana mhando yerabha, furo mhedzisiro haina kufanana patembiricha dzakasiyana, nekuti iyo foaming system uye vulcanization system inonzwa tembiricha yemadhigirii akasiyana, sisitimu inoshanduka, dhigirii rinoenderana nemusiyano, mhedzisiro yacho zvakare yakasiyana.

 

　　4, kuumba

 

　　Zvigadzirwa zverabha zvakafukidzwa zvinotevera kugadzirisa uye kuumba nzira ndeye extrusion kuumba, kuumba, kuumba ndiro, zvichingodaro, zvinoenderana nechimiro chinodiwa chechigadzirwa chakapedzwa, yakatarwa, kureba, saizi, chimiro, kuoma, ruvara rwakasiyana, pamwe neakakosha. zvinodiwa zvemadhirowa, iwe unogona kuita zvisiri-yakajairwa yakasarudzika yakasarudzika.
