Nzira dzinoverengeka dzakajairika dzirimi dzekuzivisa

1. Kupesana nehuremu hwemaganho kuwana bvunzo

Chigadzirwa chakapera chinogona kutsanangurwa, chakanyoroveswa mune imwe kana akati wandei zvinyorwa zvezvinyorwa, kuyerwa mushure mekunge tembiricha uye nguva, uye mhando yezvinyorwa zvinogona kuiswa zvinoenderana nehuremu hwekuchinja uye huwandu hwekuchinja kwekuchinja.

Semuenzaniso, akanyudzwa mumafuta zana maawa maawa makumi maviri nemana, NBR, Fluorine Rubber, Eco

2. Mhepo inopisa yekukweva bvunzo

Tora samples kubva pane zvigadzirwa zvakapera, zviise mubhokisi rekukwegura kwezuva rimwe, uye chengetedza chiitiko mushure mekukwegura. Kukwereta zvishoma nezvishoma kunogona kuwedzera zvishoma nezvishoma. Semuenzaniso, semuenzaniso, nr, uye SBR ichave brittle pamadhigirii zana nemakumi mashanu, nepo NBR Epdm achiri elastic. Kana tembiricha ichisimuka kusvika kune 180 madhigirii, iyo yakajairika NBR ichave brittle; Uye iyo HNBR ichave zvakare brittle pamadhora mazana maviri nemakumi maviri, uye iyo Fluorine Rubber uye Silicone ichine kugona kwakanaka.

3. Chutustion nzira

Tora sampuli diki uye uzvipisa mumhepo. Cherekedza chiitiko.

Kazhinji, Fluorine Rubber, Cr, CSM yakasununguka kubva pamoto, uye kunyange kana murazvo uri kupisa, idiki pane denderedzwa nr uye epdm. Ehe, kana tikanyatsotarisisa, mamiriro ekurohwa, ruvara, uye kunhuhwidza anotipawo neruzivo rwakawanda. Semuenzaniso, kana nBR / PVC yakabatanidzwa ne glue, kana paine moto wemagetsi, moto unopaza uye zvinoita kunge semvura. Izvo zvinofanirwa kucherechedzwa kuti dzimwe nguva murazvo unodzora asi Halogen-remahara-dzemahara glue zvichazvidzima kubva pamoto, izvo zvinofanirwa kuenderera mberi nedzimwe nzira.

4. Kuyera chaiyo gravity

Shandisa chiyero chemagetsi kana ongororo yekuyera, chaiyo kusvika 0.01 gramu, pamwe negirazi remvura uye bvudzi.

Kazhinji, Fluorine Rubber ane yakakura kwazvo simba rakanyanya kunaka, pamusoro pe1.1,8, uye yakawanda yeCr ec equ zvigadzirwa zvine huwandu hukuru pamusoro pe1.3. Idzi glues dzinogona kutariswa.

5. Kuderera kwetembiricha nzira

Tora sampuli kubva kuchigadzirwa chakapera uye shandisa ice yakaoma uye doro kuti ugadzire nzvimbo yakakodzera yeClyogenic nharaunda. Svina sampuli mune yakadzika tembiricha yemaminitsi 2-5 maminitsi, inzwa kupfava uye kuomarara pakupisa kwakasarudzwa. Semuenzaniso, At -40 madhigirii, iyo imwe chete tembiricha uye yekudziya mafuta silica gel uye fluorine rabara inoenzaniswa, uye silika gel iri kunyatsopora.
