Izinqubo ezintathu eziyisisekelo ngesikhathi sokuxuba irabha nomshini wokuxuba irabha

Umshini wokuxuba irabha uqukethe izinqubo ezintathu enqubweni yokuxuba irabha: Ukusonga nge-roll, i-Eating powder, i-Refining kanye ne-refining.

1. Ukugoqa imiqulu

Ngesikhathi sokuxuba, kungase kube nezimo ezine lapho kuvela khona irabha eluhlaza ku-roller yesigayo esivulekile

Isimo sokuqala senzeka lapho izinga lokushisa le-roller liphansi kakhulu noma irabha iqinile, okubangela ukuthi irabha ihlale erabhani nasesilayidini esiqongelelwe, ingakwazi ukungena esikhaleni se-roller, noma ibe yizicucu kuphela uma icindezelwa ngenkani.

Isimo sesibili senzeka lapho irabha isesimweni sokunwebeka okuphezulu, kokubili ukugeleza kwepulasitiki kanye nokuguquguquka okufanele kokunwebeka okuphezulu. Izinto zerabha zigoqwa kuphela nge-roller engaphambili ngemva kokudlula esikhaleni se-roller, okuwusizo ekusebenzeni kokuxuba kanye nokuhlakazeka kwe-ejenti ehlanganisayo ezintweni zerabha.

Isimo sesithathu senzeka lapho izinga lokushisa liphezulu kakhulu, ukugeleza kwerabha kuyanda, amandla aphakathi kwama-molecule ayancipha, futhi ukuqina namandla kwehla. Ngalesi sikhathi, ifilimu ayikwazi ukugoqa ngokuqinile i-roller bese yakha isimo esifana nesikhwama, okuholela ekuqhekekeni noma ekuqhekekeni kwe-roller, futhi ayikwazi ukuhlanganiswa.

Isimo sesine senzeka emazingeni okushisa aphezulu, lapho irabha ishintsha khona isuka esimweni sokunwebeka kakhulu iye esimweni sokugoba, cishe ingenakho ukunwebeka namandla, okwenza kube nzima ukusika izinto zerabha. Ngakho-ke, izinga lokushisa lokuxuba kufanele lilawulwe ukuze kugcinwe izinto zerabha zisesimweni esihle, okuyinto ehambisana nenqubo yokuxuba.

2. Impuphu yokudla

Isigaba sokudla impuphu sibhekisela enkambisweni yokuxuba i-compound agent nezinto ezinamathelayo. Ngemva kokuba i-rubber roller isongiwe, ukuze kuhlanganiswe ngokushesha i-compound agent ne-raber, inani elithile le-glue eqoqwe kufanele ligcinwe ekugcineni kwesikhala se-roller.

Uma kungezwa i-compound agent, ngenxa yokujika nokushintsha i-glue eqongelelekile njalo, i-compound agent ithwalwa iye emibimbi nasezimbotsheni ze-glue eqongelelekile, bese ingena esikhaleni se-roller.

Ngesikhathi senqubo yokudla ama-noodle, inani le-glue eqoqwe kumele libe lilinganiselwe. Uma kungekho-glue eqoqwe noma inani le-glue eqoqwe lincane kakhulu, ngakolunye uhlangothi, i-compound agent ithembele kuphela emandleni okusika phakathi kwe-roller yangemuva nerabha ukuze ihlikihle ezintweni zerabha, futhi ayikwazi ukungena ijule ngaphakathi kwezinto zerabha, okuthinta umphumela wokuhlakazeka; Ngakolunye uhlangothi, izithasiselo eziyimpuphu ezingakahlikihlwa erabha zizocindezelwa zibe yizicucu yi-roller yangemuva bese ziwela ethreyini yokwamukela. Uma kuyi-additi ewuketshezi, izonamathela ku-roller yangemuva noma iwele ethreyini yokwamukela, okubangela ubunzima ekuxubeni.

Uma kukhona ukunqwabelana ngokweqile kweglue, enye inhlaka izojikeleza futhi igoqeke ekugcineni kwegebe leroli, umshini wokugaya irabha, okuzoyivimbela ukuthi ingangeni esikhaleni futhi kwenze kube nzima ukuthi i-ejenti yokuxuba ixube. Inani leglue eliqoqiwe livame ukulinganiswa nge-engeli yokuxhumana (noma i-engeli yokuluma), ngokuvamile ephakathi kuka-32-45.

3. Ukucwenga nokucwenga

Isigaba sesithathu sokuxuba ukucwenga. Ngenxa yokuthamba okuphezulu kwerabha, ngesikhathi sokuxuba, izinto zerabha zigeleza kuphela ohlangothini oluzungezile eceleni kokuqondisa komshini ovulekile wokugaya, ngaphandle kokugeleza kwe-axial. Ngaphezu kwalokho, irabha egeleza ohlangothini oluzungezile i-laminar. Ngakho-ke, i-mixer yangaphakathi, ungqimba olunamathelayo olunamathela eduze ebusweni be-roller yangaphambili cishe ku-1/3 yobukhulu befilimu alukwazi ukugeleza futhi luba “ungqimba olufile” noma “ungqimba olumile” lwe-lab kneader mixers.

Ngaphezu kwalokho, inhlaka eqongelelekile engxenyeni engenhla yesikhala se-roller nayo izokwakha "indawo ye-reflux" emise okwengxenye ye-wedge. Izizathu ezingenhla zonke ziholela ekuhlakazekeni okungalingani kwe-compounding agent ezintweni zerabha.

Ngakho-ke, kuyadingeka ukudlula ezigabeni eziningi zokucwenga, ukusika ngemimese yesobunxele nesokudla, umshini wokukhipha irabha, ukugoqa noma ukusonga okunxantathu, ukunciphisa, njll., ukuze kuphulwe ungqimba olufile nendawo ye-reflux, kwenziwe ukuxuba okufanayo, futhi kuqinisekiswe ikhwalithi kanye nokufana.
