Matanho matatu ekutanga panguva yekusanganiswa kwerabha nemuchina wekusanganisa rabha

Muchina wekusanganisa rabha unonyanya kuve nematanho matatu mukusanganisa rabha: Roll kuputira, Kudya hupfu, Kunatsa uye kunatsa.

1. Roll kuputira

Panguva yekusanganiswa, panogona kunge kune mamiriro mana anogoneka apo rabha yakasvibirira inoonekwa pane roller yeguyo rakavhurika

Mamiriro ekutanga anoitika kana tembiricha yeroller yakadzikira kana kuti rabha yakaoma, zvichiita kuti rabha rigare pane rabha raunganidzwa uye mutserendende, risingakwanisi kupinda mugedhi reroller, kana kungoita zvidimbu kana radzvanywa mukati.

Mamiriro echipiri anoitika kana rabha iri mune yakakwira elastic mamiriro, ine ese epurasitiki kuyerera uye yakakodzera yakakwirira elastic deformation. Iyo rubber zvinhu inongoputirwa kumberi roller mushure mekupfuura nepakati peiyo roller spacing, iyo inobatsira pakusanganisa mashandiro uye kupararira kweiyo komputa mumiriri mune yerubha zvinhu.

Mamiriro echitatu anoitika kana tembiricha yakawandisa, iyo rubber fluidity inowedzera, iyo intermolecular masimba inoderera, uye elasticity uye simba zvinoderera. Panguva ino, iyo firimu haigoni kunyatsoputira kutenderera uye kuumba bhegi sechimiro, zvichiita kuti roller detachment kana kuputsika, uye haigoni kusanganiswa.

Mamiriro echina anoitika pakupisa kwepamusoro, apo rabha inoshanduka kubva kune yakanyungudika kusvika kune yakasvibirira mamiriro, ine inenge isina elasticity uye simba, zvichiita kuti zvive zvakaoma kutema rubber zvinhu. Saka, kutonhora kwekusanganiswa kunofanira kudzorwa kuchengetedza zvinhu zverubha muhutano hwakanaka, izvo zvinogadzirisa kusanganiswa.

2. Kudya hupfu

Chinhanho chekudya chehupfu chinoreva nzira yekusanganisa iyo inosanganiswa neiyo inonamira. Mushure mokunge rubber roller yakaputirwa, kuitira kuti ikurumidze kusanganisa musanganisi wekubatanidza murubha, imwe chiyero cheglue yakaunganidzwa inofanira kuchengetwa pamucheto wepamusoro wegeji.

Paunenge uchiwedzera mumiririri wekubatanidza, nekuda kwekuenderera mberi kwekuputika uye kuchinjwa kweglue yakaunganidzwa, iyo yakasanganiswa inotakurwa mumakwinya uye mitsetse yeglue yakaunganidzwa, uye ipapo mugomba re roller.

Munguva yekudya ma noodles, huwandu hweglue hwakaunganidzwa hunofanira kunge huri pakati nepakati. Kana pasina glue yakaunganidzwa kana huwandu hweglue yakaunganidzwa idiki zvakanyanya, kune rimwe divi, iyo inosanganisa mumiriri inongovimba neshear simba pakati peiyo yekumashure roller nerabha kuti ikwire mukati meiyo rubber zvinhu, uye haigone kupinda mukati memukati. mukati meiyo rubber material, iyo inokanganisa kupararira kwekuita; Kune rumwe rutivi, zviwedzere zvehupfu zvisina kukwizwa murubha zvichasvinwa kuita zvidimbu nerori rekumashure uye kuwira mutireyi yekugamuchira. Kana iri yekuwedzera yemvura, inonamatira kune yekumashure roller kana kuwira pane yekugamuchira tireyi, zvichikonzera kuoma mukusanganisa.

Kana paine glue yakawandisa kuunganidzwa, imwe glue inotenderera ichikunguruka kumucheto kwepamusoro kwegeji re roller, muchina wekukuya werabha, zvichidzivirira kuti isapinda pakakoromo uye kuita kuti zviome kuti musanganisi asanganise. huwandu hweglue yakaunganidzwa inowanzoyerwa nekona yekubata (kana bite angle), iyo inowanzova pakati pe32-45.

3. Kukwenenzvera nekunatsa

Nhanho yechitatu yekusanganiswa ndeye kunatsa. Nekuda kweiyo viscosity yakakwira yerabha, panguva yekusanganiswa, iyo rubber zvinhu inoyerera chete munzira inotenderera ichitevedza nzira yekutenderera yeyakavhurika mill roller, pasina axial kuyerera. Uyezve, rabha inoyerera munzira inotenderera ndeye laminar. Naizvozvo, musanganisi wemukati, iyo yekunamira iyo inonamira zvakanyanya pamusoro peiyo yekumberi roller pane inenge 1/3 yehupamhi hwefirimu haigone kuyerera uye inova "yakafa layer" kana "stagnant layer" lab kneader mixers.

Pamusoro pezvo, iyo glue yakaunganidzwa pachikamu chepamusoro chegeji re roller ichaitawo chidimbu-chakaita "reflux zone". Zvikonzero zviri pamusoro apa zvese zvinokonzeresa kupararira kusina kuenzana kweanosanganisa ajenti murubha zvinhu.

Naizvozvo, zvinodikanwa kuti upfuure nepakati pematenderedzwa akawanda ekunatsa, kucheka nekuruboshwe nekurudyi mapanga, rabha extrusion muchina, rolling kana katatu kuputira, kutetepa, nezvimwewo, kuitira kutyora yakafa layer uye reflux nzvimbo, gadzira iyo yekusanganisa yunifomu, uye chengetedza kunaka uye kufanana.
