Chinoburitsa rabha chinoshanda sedombo guru pakugadzira polymer, muchina unoshanda zvakasiyana-siyana uye wakasimba unokosha pakugadzira rabha kuti ive mapurofayi akawanda anoenderera mberi. Kushanda kwayo, kwakavakirwa papfungwa yekumanikidza zvinhu zverabha zve viscoelastic kuburikidza nedhishi rechimiro chakati, kuri nyore kwazvo. Asi, mainjiniya ayo uye hunhu hwayo hunoita kuti ive yakakosha mumaindasitiri akasiyana-siyana, kubva kumotokari kusvika kuvaka.
Hunhu Hukuru hweRubber Extruders
Zvishandiso zverabha zvemazuva ano, kunyanya zvakagadzirwa se screws, zvine hunhu hwakasiyana hunoita kuti zvikwanise kushandiswa zvakanyanya:
1. Kugadziriswa Kunogara Kuchiitwa Uye Kunoshanda: Kusiyana nemaitiro ebatch, maextruder anoshanda nguva dzose, michina yekubvisa rabha, kugamuchira rabha yakagadzirwa (kazhinji muchimiro chestrip kubva kumusanganiswa) uye ichiburitsa chimiro chakafanana. Izvi zvinoita kuti kugadzirwa kuwedzere, mhando yechigadzirwa igare yakafanana, uye kushandiswa kwezvinhu zvinobudirira pasina marara akawanda.
2. Kuchinja-chinja kwechinhu chinobuda: Nekungochinja musoro wedhiziri, chinhu chimwe chete chinoburitsa chinhu chinogona kugadzira mhando dzakasiyana-siyana dzemaumbirwo akasiyana-siyana—akasimba, asina chinhu, kana akaomarara. Izvi zvinosanganisira zvisimbiso zviri nyore, zvishongo zvemotokari zvakaoma, matayi edhiziri, uye machubhu ane dhayamita dzakasiyana.
3. Kusanganisa Kwakasimba uye Kubatana: Dhizaini yemasikuruu, kazhinji nezvikamu zvekusanganisa kana mapini, inopa simba rakakura rekuchekerera nekudzvanya. Izvi zvinoita kuti rabha iite zvakafanana, zvichiparadzira zvinhu zvakaita secarbon black zvakaenzana uye zvichiita kuti viscosity uye hunhu hwayo zvienderane mukati mechinhu chinobuda.
4. Kudzora Kupisa uye Kugadzirira Kuputika: Bharero rekubuda rakakamurwa kuita nzvimbo dzakasiyana-siyana dzinodzorwa nekupisa. Izvi zvinobvumira kutarisirwa kwakanyatsojeka kwechimiro chekupisa cherabha, zvichiisa plaster zvakanaka kuti chibude. Zvishandiso zvemazuva ano zvinowanzobatanidzwa nemitsetse yekupisa-mhepo kana microwave, zvichigadzirira chimiro kuti chibude nekukurumidza.
5. Kuchinjika kuMamiriro Ezvinhu: Zvinoshandiswa pakugadzira zvinhu zvinogona kugadzira mhando dzakasiyana dzemakomputa erabha, kubva kurabha yechisikigo (NR) nerabha yestyrene-butadiene (SBR) kusvika kumapolymers akasarudzika akadai seethylene propylene diene monomer (EPDM) nesilicone. Kugadziriswa kwekumhanya kwescrew, tembiricha, uye dhizaini yedivha kunogadzirisa hunhu hwakasiyana hwekuyerera kwezvinhu (rheology).
6. Kubatanidzwa neMidziyo Yepasi: Simba guru kugona kwayo kushanda semoyo wemutsara wekugadzira. Inobatanidzwa zvakanaka nemaitiro e roller die ekushandisa matayi, crossheads dzewaya netambo, ma cutters, matangi ekutonhodza, uye masisitimu e continuous vulcanization, zvichiita kuti igadzire otomatiki.
Zvikumbiro Zvikuru muIndasitiri
Hunhu hwakasiyana hwezvinhu zvinoburitsa rabha zvinoshandura kuita mashandisirwo akakosha muzvikamu zvakasiyana-siyana:
· Kugadzira Matayi: Iri ndiro rimwe remashandisirwo akakosha. Zvishandiso zvekugadzira matayi zvakagadzirwa nehunyanzvi, zvinowanzova nema roller dies, zvinogadzira mapatani chaiwo ekugadzira matayi uye ma profiles emativi. Zvimwe zvinoshandiswa kugadzira ma inner liners, apex strips, uye zvikamu zvakasiyana-siyana zverabha mukati metai. Vagadziri vemichina yekugadzira matayi muChina，Kukwanisa kubvisa pamwe chete zvinhu zvakasiyana zverabha kwakakosha pano.
· Zvikamu zveMotokari: Indasitiri yemotokari inonyanya kushandisa rabha dzakabuda mumidziyo yekuvhara masisitimu (zvisimbiso zvemasuo, zvisimbiso zvemahwindo, zvisimbiso zvematrunk), mapombi (anotonhodza, anopinza mweya), mabhutsu eguruva, uye trim. EPDM inowanikwa zvakanyanya pano nekuda kwekusagadzikana kwayo mumamiriro ekunze.
· Kudzivirira Waya neCable uye Kuvhara: Vachishandisa die ye crosshead, ma extruders anofukidza waya dzemhangura kana dzearuminiyamu nema insulating layers (semuenzaniso, kubva kuEPR, XLPE) uye majaketi ekudzivirira ekunze (kazhinji kubva kuPVC kana halogen-free raber compounds). Kushandiswa uku kunoda kunyatsojeka mu concentricity uye ukobvu.
· Zvinhu Zverabha Zvakajairika: Chikamu ichi chakakura chinosanganisira mapombi ehydraulic nepneumatic, machubhu akasiyana-siyana ekushandisa pakurapa kana mumaindasitiri, tambo dzerabha dzezvisimbiso zvemichina, magasket efiriji, uye kubvisa mamiriro ekunze akaoma kana esponji ezvivakwa.
· Kuvaka uye Zvivakwa: Rabha inoshandiswa pakuwedzera majoini emabhiriji nezvivakwa, silicone roller covering strips yemichina yemachira, ma membrane ekudzivirira mvura, ma gaskets e glazing, uye ma profiles e denga.
· Zvinhu Zvinoshandiswa Nevatengi: Mashandisirwo acho anotangira pamagasket emidziyo yemumba nezvishandiso zvekushandisa kusvika kumidziyo yemitambo nezvitsigiro zveshangu.
Mukupedzisa, muchina wekubvisa rabha imhando yekugadzirwa kunobudirira uye kunoramba kuripo. Hunhu hwayo hwekusiyana-siyana, kubuda kunoramba kuripo, uye kudzora maitiro chaiwo kunogadzirisa matambudziko makuru ekugadzira rabha. Sezvo sainzi yezvinhu ichifambira mberi uye kudiwa kwezvigadzirwa zverabha zvakaoma uye zvinoshanda zvakanyanya kuri kukura, muchina wekubvisa rabha unoramba uchichinja—uchibatanidza kudzora maitiro kwakangwara, magadzirirwo emhando yepamusoro, uye kubatanidzwa kuri nani nemasisitimu ari pasi. Hazvina mubvunzo, unoramba uri muchina unokosha mukushandura macompounds erabha asina kugadzirwa kuita zvinhu zvakakosha zvinotsamira pahupenyu hwemazuva ano nemaindasitiri.
