Izinqubo ezintathu eziyisisekelo ngesikhathi sokuxuba kwenjoloba nomshini wokuxuba werabha

Umshini wokuxuba werabha ngokuyisisekelo uqukethe izinqubo ezintathu kwinqubo yokuxuba kwerabha: Roll ukugoqa, ukudla okudliwayo, ukucwilisa nokucwilisa.

1. Roll ukugoqa

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

Isimo sokuqala senzeka lapho izinga lokushisa le-roller liphansi kakhulu noma irabha linzima, lidala irabha ukuze lihlale kurabha eliqongelelwe bese liyahluleka ukungena kwi-roller gap, noma libe yizicucu ezicindezelwe kakhulu lapho zicindezelwa.

Isimo sesibili senzeka lapho irabha isesimweni esiphakeme kakhulu, ngokugeleza kwepulasitiki nokuguquguquka okuphezulu okuphezulu. Izinto zenjoloba zisongwe kuphela ngokuzungeza i-roller yangaphambili ngemuva kokudlula kwi-roller sppecing, okuzuzisa ukuxubana kwemisebenzi nokuhlakazwa kwe-ejenti ehlanganisiwe ezintweni zenjoloba.

Isimo sesithathu sivela lapho izinga lokushisa liphezulu kakhulu, ushukela werabha uyanda, amandla ahlukahlukene ancipha, kanye nobunye nokuncipha namandla namandla okuqina. Ngalesi sikhathi, ifilimu alikwazi ukugoqa ngokuqinile nxazonke i-roller futhi yakha isikhwama esifana nokwakheka, okuholela ekuwohlokeni kwe-roller noma ukuqhekeka, futhi akunakuxutshwa.

Isimo sesine senzeka emazingeni okushisa aphezulu, lapho irabha liguquka lisuka esimweni esiphakeme kakhulu esimweni se-viscous, cishe kungabi bunzima namandla, okwenza kube nzima ukusika impahla yerabha. Ngakho-ke, izinga lokushisa lokuxuba kufanele lilawulwe ukuze ligcine impahla yerabha isesimweni esihle, esivumelana nenqubo yokuxuba.

2. Ukudla i-powder

Isigaba sokudla powder sisho inqubo yokuxuba i-ejenti ehlanganisiwe ezintweni ezinamathela. Ngemuva kokuthi i-roller roller esongelwe, ukuze ixube ngokushesha i-ejenti ehlanganisiwe kwirabha, inani elithile le-glue eliqoqiwe kufanele ligcinwe ekugcineni kwegebe le-roller.

Lapho ungeza i-ejenti ehlanganisiwe, ngenxa yokuvutha okuqhubekayo nokubuyiselwa kwe-glue eqoqiwe, umenzeli ohlanganisiwe uthwalwa emibimbini nasemikhombeni ye-glue eqoqiwe, bese kungena kwi-roller gap.

Ngesikhathi senqubo yokudla ama-noodle, inani le-glue eqoqiwe kumele lilinganiselwe. Lapho ingekho i-glue eqoqiwe noma inani le-glue eqoqiwe lincane kakhulu, ngakolunye uhlangothi, i-ejenti ehlanganisiwe ithembela ukungena ngaphakathi kwe-roller, futhi ayikwazi ukungena ekutholeni impahla yerabha, okuthinta umphumela wokuhlakazeka; Ngakolunye uhlangothi, izithasiselo eziyimpuphu ezingakaze zikhuhlwe enjoloba zizofakwa izingcezu nge-roller engemuva bese ziwela ku-tray etholayo. Uma kungukungezelelwa koketshezi, kuzokunamathela ku-roller engemuva noma kuwele ku-tray etholayo, okubangela ubunzima ekuxubeni.

Uma kunokunqwabelana ngokweqile kwe-glue, enye ye-glue izojikeleza futhi igxile ekugcineni kwe-roller gap, umshini wokugaya irabha, inani le-glue eliqoqiwe livame ukulungiswa yi-angle yokuxhumana (noma i-bite angle), okuvame kakhulu phakathi kuka-32-45.

3. Ukucoca futhi kucwengeke

Isigaba sesithathu sokuxuba siyacolisa. Ngenxa ye-viscosity ephezulu yerabha, ngesikhathi sokuxuba, impahla yerabha igeleza kuphela endaweni ejikelezayo eceleni komjikelezo wokujikeleza we-roller evulekile, ngaphandle kokugeleza kwe-axial. Ngaphezu kwalokho, irabha ligeleza esiqondisweni esikhethekile yi-laminar. Ngakho-ke, i-mixer yangaphakathi, ungqimba olunamathela anamathela eduze kobuso bangaphambili cishe ngo-1/3 wokuqina kwefilimu awukwazi ukugeleza futhi ube ungqimba "ofile" noma "ungqimba olufile"

Ngaphezu kwalokho, i-glue eqoqiwe engxenyeni engenhla ye-roller gap nayo izokwakha i- "Reflux Zone ye-Wedge ngokwengxenye. Izizathu ezingenhla bonke baphumela ekuhlakazekeni okungalingani kwe-ejenti ehlanganisiwe ezintweni ezibonakalayo zenjoloba.

Ngakho-ke, kuyadingeka ukuthi kudlule imijikelezo eminingi yokucolisiswa, ukusika ngemimese yesokunxele nakwesokudla, umshini wokukhishwa kwenjoloba, ukudonsa, ukuqeda indawo efile kanye ne-Reflux, bese uqinisekisa ikhwalithi nokufana.
