Rubha chinhu chinoshandiswa nevakawanda uye chinochinjika chinoshandiswa mukugadzira zvinhu zvakasiyana-siyana, zvinosanganisira mabhande erastiki, shangu, kepisi dzekutuhwina, uye hosi.Kutaura zvazviri, kugadzirwa kwemavhiri emotokari kunodya inenge hafu yerabha yose inogadzirwa.Tichifunga nezve kukosha kwayo, zvakakodzera kuongorora maitiro ekugadzira rabha uye kwaakabva.Ichi chinyorwa chinotarisa kusuma nezve kwakabva rubber,nzira yekugadzira rubber,zvikumbiro zverabha, rudzi rwerabhauyesei kusarudza rabhasezvinhu zvechigadzirwa.
Kwakabva rubber
Kweanopfuura mireniyumu, vanhu vave vachishandisa unhu hwerabha hwakasimba uye hunochinjika kugadzira zvinhu zvakasiyana-siyana.Pakutanga yakatorwa kubva kuzvinhu zvechisikigo, asi nekuda kwerabha yakawedzera kufarirwa uye kudiwa kunokwira kwakatungamira kune vanhu vanofarira kugadzira rabha mumarabhoritari anogona kugadzira rabha rine hunhu hwakawanda.Mazuvano, yakawanda yerabha yatinoshandisa inogadzirwa nekugadzira.
Natural Rubber Yakagadzirwa Sei
Mhando dzakasiyana dzeartificial rabha dzinoshanda akasiyana mabasa uye nekudaro, nzira dzekugadzira dzinogona kusiyana zvakanyanya.Panzvimbo yekuvimba nezviwanikwa, aya machira anogadzirwa kuburikidza nemakemikari maitiro senge polymerization.Zvakajairika sosi zvinhu zvakaita semarasha, oiri, uye mahydrocarbon anonatswa kugadzira naphtha.Naphtha inozosanganiswa negasi rechisikigo kugadzira mon iyo inogadziriswazve kuita cheni dzepolymer uchishandisa chiutsi uye vulcanization kugadzira rabha.
Rubber process
1.Compounding
Kubatanidza makemikari ekuwedzera mubhesi rerabha kunogona kuburitsa makomisheni erabha ane zvimiro zvakawedzeredzwa.Aya makemikari anogona kudzikamisa chimiro chepolymer kana kuwedzera kusimba kwerabha.Pamusoro pezvo, maitiro ekubatanidza anogona dzimwe nguva kuwedzera kusimba kwerabha, zvichikonzera mutengo wakaderera wekupedzisira.
2.Kusanganisa
Mukuita kwakafanana nekubatanidza, zvinowedzera zvinosanganiswa nerabha muchikamu ichi.Kuti ive nechokwadi chekugovera kwakakodzera kwezvigadzirwa uye kudzivirira kupisa, vasanganisi vane hunyanzvi vanoita iyi nzira mumatanho maviri.Chekutanga, vanhu vanogadzirira masterbatch ine additives senge kabhoni nhema.Kana rabha ratonhora pasi, vanounza makemikari anodiwa ekuputira.
3.Shaping
Vagadziri vanogona kushandisa nzira dzakasiyana-siyana dzekugadzira senge coating, extrusion, casting, calendering, uye molding kugadzira akawanda ezvigadzirwa.Kusarudzwa kwemaitiro ekuumba kunoenderana nezvinodiwa chaizvo zvechigadzirwa chekupedzisira.
4.Vulcanization
Kuti iwedzere kusimba uye kusimba kwayo, rabha inorapwa kupisa kunonzi vulcanization.Izvi zvinosanganisira kupisa rabha, kazhinji nesarufa, kugadzira zvisungo zvekuwedzera pakati pemamorekuru, zvichiita kuti asanyanya kuparadzaniswa.Kutevera vulcanization, chero hurema hunobviswa, uye rabha rinoumbwa kana kuumbwa muchigadzirwa chaunoda.Rubber inoramba iri yakakosha kugadzirwa ine akasiyana maapplication, uye Ruicheng inopa huwandu hwakasiyana hwemhando yepamusoro zvigadzirwa zverabha, zvinosanganisira matting, zvisimbiso, uye extrusions.
Rubber application
Imba:Rubha inowanzoshandiswa mukugadzira shangu, bhutsu, uye dzimwe shangu nekuda kwekusimba kwayo uye inodzivirira mvura.
Motokari: Rubha rinoshandiswa mumhando dzakasiyana dzemotokari senge hose, mabhandi, bushings, uye injini yekumisikidza yekudonhedza kunyorova uye kubatwa nekuvhunduka.Kunyanya matayi, rabha chinhu chakakosha mukugadzira matai emotokari, mabhasikoro, nedzimwe mota.
Zvishandiso zvekurapa: Nekuda kwehuzhinji hwakanaka hwerabha, minda yekurapa muindasitiri yese iri kutora zvinhu zvekushandisa kwakasiyana siyana.Hunyanzvi hwezvokurapa, hunosanganisira nzeve, mhino, uye nyanzvi dzehuro, cardiology, oncology, ophthalmology, kuvhiyiwa kwepurasitiki, uye kuvhiyiwa kwese kuri kutendeukira kumvura yesilicone rabha uye yekurapa rabha kuumbwa kwekushandisa kamwe chete uye kushandiswazve kwemidziyo yekurapa.
Panguva imwecheteyo, Rubber inoshandiswa mukugadzira michina yekurapa yakaita segirovhosi, tubing, uye zvisimbiso nekuda kwekuenderana kwayo uye kuchinjika.
Sporting Goods: Rubha rinoshandiswa mukugadzirwa kwemidziyo yemitambo yakaita semabhora, grips, uye padding nekuda kwekusimba kwayo uye kupikisa kuramba.
Mhando dzakajairika dzerubha
Natural rubber
Rabha rechisikigo rinowanikwa nekubvisa muto wemvura, unonzi latex, kubva mumhando dzakasiyana dzemiti, nemuti weHevea brasiliensis uriwo wekutanga.Maitiro ekuunganidza latex anosanganisira kucheka makwati uye kuunganidza muto mumakomichi, maitiro anozivikanwa sekutapa.Kuti udzivise kusimba, ammonia inowedzerwa, inoteverwa neasidhi kubvisa rabha kuburikidza nekubatana, izvo zvinotora maawa gumi nemaviri.Musanganiswa wacho unobva wapfuura nemuma rollers kuti abvise mvura yakawandisa, uye zvidimbu zverabha zvinoomeswa nekuzvirembera pamusoro pemaraki mumasmokehouses kana kuomeswa nemhepo.
Synthetic rubber
Masayendisiti echiGerman akagadzira rabha rekugadzira panguva yeHondo Yenyika I nekuda kwekushomeka kwemasikirwo erabha masosi.Nepo pakutanga yemhando yakaderera pane yakasikwa rabha, rekugadzira rabha rakafambira mberi nekufamba kwenguva kuburikidza nekutsvaga nekusimudzira.Mazuva ano, rabha yekugadzira yakangogara yakasimba uye yakavimbika seyakafanana nayo yakasikwa.Musiyano mukuru uripo pakati peyakaita uye yakasikwa rabha iri muchokwadi chekuti synthetic rabha inogadzirwa nekubatanidza polymer mamorekuru murabhoritari.Iye zvino vazhinji vanogadzira vanoda kushandisa synthetic rubber.
Zvakanakira rubber
Flexibility uye elasticity: Rubber inozivikanwa nekukwirira kwayo uye kushanduka kwayo, ichibvumira kuti iparadze pasi pekunetseka uye kudzokera kuchimiro chayo chepakutanga kana kushungurudzika kwabviswa.Ichi chivakwa chinoita kuti rabha ive yakanaka kune maapplication uko kusimba uye kuchinjika kunodiwa, senge mumatairi, zvisimbiso, uye zvekuvhunduka.
Kuramba kupfeka uye kubvarura: Rubber inoratidzira kupikisa kwakanyanya kune abrasion, kupfeka, uye kubvarura, zvichiita kuti igare uye inogara kwenguva refu.Ichi chivakwa chinoita kuti rabha rikodzere maapplication anosanganisira kugara uchikweshana uye kuratidzwa kune hutsinye nharaunda, senge mabhandi ekutakurisa, hosi dzemaindasitiri, uye zvinhu zvemotokari.
Kuderedza ruzha: Rubha inogona kunyatso kudzikisa kuzunguzika uye kuderedza ruzha, ichiita kuti ive yakakodzera kushandiswa muzvishandiso uko kudzikisa ruzha kwakakosha, senge muzvikamu zvemotokari uye zvekuvakisa.
Shock absorption: Rubber ine yakanakisa kuvhundutsa zvinhu, izvo zvinoita kuti ive yakakodzera kushandiswa muzvigadzirwa zvakaita seshangu, midziyo yemitambo, uye vibration yekuzviparadzanisa nevamwe.
Aya mabhenefiti anoita kuti rabha rive chinhu chakakosha mumaindasitiri akasiyana siyana, anosanganisira emotokari, kuvaka, zvemagetsi, hutano, uye zvinhu zvevatengi.
Summary
Chinyorwa chacho chakaongorora hunhu hwerabha, chakavheneka nezvekwakabva, munyoreri uye zvakanakira, uye kusuma rabha akajairika akasiyana mafomu ayo anogona kutora mumaindasitiri maapplication.tinovimba kuti chinyorwa ichi chakubatsira kuona kuti ingani mashandisirwo erabha aripo chaizvo.Nerabha, mikana haina magumo.Kana uchida kuziva zvakawanda,ndapota taura nesu!
