Taw qhia
Polypropylene (PP) pob qij txha ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, suav nrog cov kav dej, kev tsim kho, thiab kev ua tshuaj lom neeg. Tsab ntawv xov xwm no tshawb txog cov txheej txheem tsim khoom thiab kev tswj xyuas kev ua tau zoo koom nrog hauv kev tsim cov pob qij txha PP, qhia txog lawv qhov tseem ceeb hauv kev ua kom muaj kev sib raug zoo thiab ruaj khov.
Kev xaiv raw khoom
Xaiv txoj cai PP Resin
Cov txheej txheem tsim khoom pib nrog kev xaiv cov khoom tsim nyog PP. Cov qib sib txawv ntawm PP muaj ntau theem ntawm lub zog, hloov tau yooj yim, thiab tsis kam mus rau tshuaj. Cov neeg tsim khoom yuav tsum xaiv cov resin uas zoo tshaj plaws rau daim ntawv thov.
Extrusion txheej txheem
1. Khoom siv Extrusion
Cov PP resin raug xaiv yog yaj thiab extruded rau hauv cov duab xav tau. Cov txheej txheem no tuaj yeem koom nrog kev tsim cov kav dej, fittings, lossis lwm yam sib koom ua ke. Kev tswj xyuas qhov kub thiab txias yog qhov tseem ceeb heev kom ua tiav cov khoom xav tau.
2. Moulding ntawm cov khoom sib txuas
PP pob qij txha feem ntau muaj ob peb yam, xws li cov qhov (socket) thiab cov khoom sib txuas. Cov khoom no yog molded cais thiab tom qab sib dhos rau hauv qhov kawg sib koom ua ke. Kev txhaj tshuaj molding yog ib txoj hauv kev siv rau lub hom phiaj no.
Kev sib dhos thiab vuam
1. Qhov (socket) Fusion Vuam
Ib qho ntawm cov txheej txheem tseem ceeb rau kev sib txuas PP pob qij txha yog lub qhov (socket fusion welding). Hauv cov txheej txheem no, cov khoom sib koom ua ke yog rhuab mus rau lawv qhov chaw melting, thiab tom qab ntawd lawv tau koom ua ke. Kev siv vuam tsis zoo thiab cov txheej txheem yog qhov tseem ceeb los tsim kom muaj kev sib txuas ruaj khov thiab tsis muaj paug.
Kev Tswj Xyuas Zoo
1. Dimensional soj ntsuam
Txhua PP sib koom ua ke dhau qhov kev tshuaj ntsuam xyuas kom ntseeg tau tias nws ua tau raws li qhov kev cia siab. Qhov no suav nrog ntsuas qhov loj me xws li sab hauv thiab sab nraud, phab ntsa thickness, thiab tag nrho ntev.
2. Kev tshuaj xyuas qhov muag
Kev tshuaj xyuas qhov muag yog qhov tseem ceeb los txheeb xyuas cov teeb meem pom, xws li cov kab nrib pleb, huab cua npuas, lossis qhov tsis sib xws. Cov pob qij txha uas muaj qhov muag tsis pom kev raug tsis lees paub los tswj cov qauv zoo.
3. Kev kuaj pom
Txhawm rau lav kev ua haujlwm tsis muaj paug, PP cov pob qij txha yuav raug kuaj xyuas. Qhov no tuaj yeem cuam tshuam nrog kev sib koom ua ke nrog huab cua lossis dej thiab saib xyuas rau txhua qhov kev poob siab, uas yuav qhia tau tias xau.
Quality Assurance
1. Kev kuaj Batch
Cov neeg tsim khoom feem ntau ua cov kev sim batch los ntawm kev xaiv ib qho piv txwv ntawm PP pob qij txha los ntawm kev tsim khoom thiab ua rau lawv nruj heev. Qhov no yuav pab kom muaj kev sib raug zoo ntawm txhua yam khoom.
2. Ua raws li cov qauv
PP sib koom ua lag luam yuav tsum ua raws li cov qauv kev lag luam thiab cov kev cai los lav kev nyab xeeb thiab kev ntseeg siab ntawm lawv cov khoom. Kev ua raws li cov qauv xws li ASTM F2620 yog qhov tseem ceeb.
Xaus
Kev tsim cov pob qij txha polypropylene koom nrog kev ua tib zoo tswj cov txheej txheem uas pib nrog kev xaiv cov khoom siv raw thiab ua tiav hauv kev tswj xyuas zoo. Cov txheej txheem tsim khoom tsim nyog, nrog rau kev tswj hwm nruj, yog qhov tseem ceeb los tsim cov pob qij txha PP uas txhim khu kev qha, ruaj khov, thiab muaj peev xwm ua tau raws li qhov xav tau ntawm ntau yam kev siv. Kev ruaj ntseg zoo thiab ua raws li cov qauv kev lag luam yog ib qho tseem ceeb rau kev xa cov khoom zoo PP pob qij txha rau lub khw.
