Iinkqubo ezintathu ezisisiseko ngexesha lokudibanisa irabha kunye nomatshini wokudibanisa irabha

Umatshini wokudibanisa irabha ngokusisiseko unenkqubo ezintathu kwinkqubo yokudibanisa irabha: roll, utyale umgubo, ukucokisa kunye nokucoca.

I-1. Qengqa isongo

Ngexesha lokuxuba, kunokubakho iimeko ezine ezinokwenzeka apho irabha yoluhlaza ivela kwi-rolleller yemilinga evulekileyo

Imeko yokuqala yenzeka xa i-roll chell iphantsi kakhulu okanye irabha inzima, ibangela ukuba irabha ihlale kwirabha yerabha eqokelelweyo, engakwazi ukufaka i-roller gap, okanye kuphela njengeziqwengana xa icinezelwe ngenkani.

Imeko yesibini yenzeka xa irabha ikwimo ephezulu ye-elastic, kunye nokuhamba kweplastiki kunye nokuphumelela okufanelekileyo kweplastiki. Isixhobo serabha sisongelwe kuphela i-roller ngaphambili emva kokudlula kwi-roller sping, enokuba yingenelo ekudibaniseni imisebenzi kunye nokusasazeka kwearhente yokudibanisa kwi-arhente yokudibanisa.

Imeko yesithathu yenzeka xa iqondo lobushushu liphezulu kakhulu, ulwelo lwerabha luyanda, imikhosi ye-interpoleculam ihla, kunye nokuqina kunye namandla okunciphisa. Ngeli xesha, ifilimu ayinakusonga ngokuqinileyo kwi-roller kwaye yenze ibhegi efana ne-roller yokwahlula okanye yokuqhekezwa, kwaye ayinakudityaniswa.

Imeko yesine yenzeka kumaqondo obushushu aphezulu, apho iinguqu zerabha zikwimo ye-elastic ukuya kwi-viscous State, phantse akukho ngqiqweni namandla, kuyenza kube nzima ukusika izinto zerabha. Ke, ubushushu bomxube kufuneka bulawulwe ukugcina izinto zerabha zikwimo elungileyo, elungele inkqubo yokuxuba.

2. Ukutya umgubo

Inqanaba lokutya umgubo libhekisa kwinkqubo yokuxuba iarhente yokudibanisa kwimpahla yokuthambelela. Emva kokuba i-roller yerabha isongelwe, ukuze idibane ngokukhawuleza iarhente yokudibanisa kwirabha, inani elithile leglue eqokelelweyo kufuneka igcinwe kwindawo ephezulu ye-roller.

Xa uyongeza iarhente yokudibanisa, ngenxa yokuqhushumba okuqhubekayo kunye nokutshintshwa kweglue eqokelelweyo, iarhente yokudibanisa ithwalwa kwii-wrinkles kunye ne-grooves yeglue eqokelelweyo, emva koko yangena kwi-rooller gap.

Ngexesha lenkqubo yokutya noodles, isixa seglu esiqokelelweyo kufuneka simodareyitha. Xa kungekho glue eqokelelweyo okanye inani leglue eliqokelelweyo lincinci, kwelinye icala, iarhente yokudibanisa ixhomekeke kuphela kwi-roller ye-Shear, kwaye ichaphazela ubunzulu bezinto zerabha, ezichaphazela isiphumo serabha; Kwelinye icala, iikopi ezingalunganga ezingakhange zidinwe kwirabha ziya kufakwa iziqwenga zeroller kwaye ziwele kwitreyi efunyenweyo. Ukuba luyinto eyongeziweyo, iya kunamathela kwi-roller engasemva okanye iwele kwitreyi efunyenweyo, ebangela ubunzima ekuxubeni.

Ukuba kukho ukuqokelela kakhulu kweglue, ezinye zeglue ziya kujikeleza kwaye ziqengqele kwisiphelo esiphezulu se-roller rall, irabha yerabha yerabha, ikhuselekile kwi-Glue yeGlue (okanye i-BITE), ephakathi kwe-32-45.

3. Ukucoca kunye nokuhlaziywa

Inqanaba lesithathu lokuxuba liyaphucula. Ngenxa yokuvalelwa okuphezulu kwerabha, ngexesha lokuxuba, irabha ihamba kuphela kwisikhokelo solwaluko kwindawo yokujikeleza ye-roller mil, ngaphandle kokuhamba nge-axial. Ngapha koko, irabha ephuma kwindawo yolwaphulo-mthetho yiLaminare. Ke ngoko, umxube wangaphakathi, umaleko wobumbethe obunembethe kwi-roller engaphambili malunga ne-1/3 yobukhulu beefilimu ayinakuhamba kwaye iba ngumxube we-Lab.

Ukongeza, iglu eqokelelweyo kwinxalenye ephezulu ye-roller guap iza kwenza i-Lodge-Godge-Godge. Ezi zizathu zilapha ngasentla zonke zikhokelela ekusasazeni okungalinganiyo kwearhente yokudibanisa kwi-raber.

Therefore, it is necessary to go through multiple rounds of refining, cutting with left and right knives, rubber extrusion machine,rolling or triangular wrapping, thinning, etc., in order to break the dead layer and reflux area, make the mixing uniform, and ensure the quality and uniformity.
