Koj puas paub tsib txoj hauv kev kom tsis txhob txhaj tshuaj welding?

Thaum cov yas molten sib ntsib nyob rau hauv pwm kab noj hniav nyob rau hauv daim ntawv ntawm ntau yam strands vim inserts, qhov, cov cheeb tsam uas discontinuous txaus tus nqi, cov cheeb tsam nrog interrupted filling cov ntaub ntawv txaus, thiab thaum lub rooj vag txhaj filling tshwm sim, linear weld marks yuav raug tsim vim. tsis tiav fusion. Lub hav zoov ntawm cov cim weld tau ua rau tsis muaj zog ntawm cov khoom siv kho tshuab. Cov txheej txheem los kov yeej cov cim vuam yog qhov tseem ceeb tib yam li txoj kev los txo cov khoom lag luam kev nyuaj siab.
1, Khoom siv
Plasticization tsis zoo thiab qhov kub tsis sib xws tuaj yeem ua rau lub voj voog molding ntev thiab ua kom cov yas ua tiav ntau dua. Yog tias tsim nyog, hloov lub tshuab nrog lub peev xwm loj plasticization.
2, pwm
(1) Yog tias pwm kub qis dhau lawm, pwm pwm yuav tsum tau nce kom tsim nyog lossis qhov kub hauv zos ntawm qhov sib koom ua ke yuav tsum tau nce siab.
(2) Txoj kev ntws me me, nqaim dhau los yog ntiav dhau, thiab qhov dej txias me me. Qhov loj ntawm cov dej ntws channel yuav tsum tau nce ntxiv txhawm rau txhim kho kev ua haujlwm ntawm cov dej ntws, thiab qhov ntim ntawm cov khoom txias zoo yuav tsum tau nce ntxiv rau tib lub sijhawm.
(3) Txhim kho lossis txo lub rooj vag seem thiab hloov lub rooj vag txoj haujlwm. Thaum qhib lub rooj vag, sim kom tsis txhob muaj cov yaj uas ntws los ntawm qhov ntxig thiab lub qhov. Sim kho, tsiv teb tsaws lossis ntxiv nres tsis rau lub rooj vag nrog kev txhaj tshuaj molding. Sim tsis txhob siv ntau lub rooj vag lossis tsawg dua.
(4) Cov pa tsis zoo lossis tsis muaj qhov tso pa tawm. Lub tso pa tawm yuav tsum qhib, nthuav dav lossis dredged, suav nrog kev siv cov ntxig thiab ejector tus pin qhov khoob rau qhov tso pa tawm.
3, txheej txheem
(1) Ua kom lub zog txhaj tshuaj thiab ncua sij hawm txhaj tshuaj.
(2) Kho qhov kev txhaj tshuaj nrawm: kev kub ceev tuaj yeem ua rau cov khoom molten ncav cuag qhov sib txuam yam tsis muaj cua txias, thiab qhov ceev ceev tuaj yeem ua rau huab cua hauv pwm kab noj hniav muaj sij hawm tso tawm.
(3) Kho qhov kub thiab txias ntawm lub taub hau: qhov kub thiab txias, tsis tshua muaj viscosity ntawm cov yas, cov qauv ntws zoo, thiab cov kab nyias nyias; Tsawg kub txo qhov decomposition ntawm gaseous tshuaj.
(4) Tus neeg sawv cev tso tawm yuav tsum siv tsawg li tsawg tau, tshwj xeeb tshaj yog tus neeg tso tawm uas muaj silicon, txwv tsis pub cov khoom ntws tsis tuaj yeem raug fused.
(5) Txo cov clamping quab yuam kom yooj yim tso tawm.
(6) Ua kom cov ntsia hlau ceev kom txo cov viscosity yas; Ua kom lub nraub qaum kom nce qhov ntom ntawm cov yas.
4, Cov khoom siv raw
(1) Cov khoom siv raw yuav tsum qhuav thiab cov kua dej ntxiv hauv cov mis yuav tsum raug txo kom tsawg.
(2) Lubricants thiab stabilizers yuav tsum tau muab ntxiv kom zoo rau cov yas uas muaj dej tsis zoo los yog kub siab, thiab cov yas uas muaj fluidity zoo los yog kub kub yuav tsum tau siv thaum tsim nyog.
5, Khoom tsim
(1) Cov phab ntsa tuab me me, yog li cov khoom yuav tsum tau ua kom tuab kom tsis txhob kho ntxov ntxov.
(2) Yog tias txoj hauj lwm ntawm qhov ntxig tsis raug, nws yuav tsum tau kho.
