Raws li ib txoj haujlwm zais cia, txoj kev txhim kho hauv tsev yog qhov tseem ceeb heev. Tam sim no, muaj ntau lub npe ntawm cov kav dej hauv khw, thiab cov ntsiab lus muag ntawm cov khoom kuj yog tag nrho ntawm kev dag. Cov khoom xws li tshuaj tua kab mob thiab ntau txheej txheej muaj ntau. Rau feem ntau cov neeg siv khoom zoo tib yam, lawv tsis paub yuav xaiv yuav cov khoom zoo li cas.
Qhov tseeb, thaum peb yuav cov khoom, peb yuav tsum saib cov ntsiab lus los ntawm kev lag luam, dab tsi yog qhov tseem ceeb, dab tsi yog qhov thib ob, dab tsi yog icing ntawm lub ncuav mog qab zib, thiab dab tsi yog superfluous, koj tuaj yeem yuav nws thaum koj paub tag nrho cov no hauv koj cov khoom. siab Koj txaus siab rau cov khoom. Tom ntej no, cia peb tham txog qhov tshwm sim thiab qhov tseem ceeb ntawm PPR dej yeeb nkab lag luam.
1. Hais txog xim
Cov xim yooj yim ntawm cov yeeb nkab dej tsis muaj dab tsi ua rau qhov zoo ntawm cov yeeb nkab dej. PP-R raw khoom yog xim tsis muaj xim thaum nws yog thawj zaug tsim, uas yog, nws yog pob tshab, thiab nws yuav tsum tau xim los ntawm kev ntxiv xim masterbatch. Tau kawg, cov kav dej dawb tau ntxiv nrog cov xim dawb masterbatch, thiab nws tsis muaj dab tsi ua nrog seb nws puas yog ntshiab lossis tsis.
2. Hais txog qhov loj
Thawj qhov uas yuav tsum paub yog tias txoj kab uas hla ntawm 4-point raj yog me me, thiab txoj kab uas hla ntawm 6-point raj yog loj. Tus nqi ntawm 6-point raj yog kim dua li ntawm 4-point raj. Puas yog tus nqi kim yuav tsum zoo? Nws tuaj yeem hais tau, tab sis nws tsis yog qhov tseeb heev. Koj yuav tsum to taub qhov twg nws kim heev.
Lub 6- taw tes yeeb nkab muaj ib txoj kab uas hla loj dua 4- cov yeeb nkab taw tes, yog li tus nqi tsim khoom yog siab dua me ntsis, thiab qhov txiaj ntsig tiag tiag nws coj yog qhov ntws ntawm cov yeeb nkab dej loj dua. Puas yog tus nqi ntws zoo? Tau kawg nws yog.
Txawm li cas los xij, qee tus neeg siv 6- cov kav dej hauv tsev, tab sis lub ntsuas dej yog 4- taw tes interface, uas poob nws lub ntsiab lus. Yog li yuav xaiv li cas? Nws yog ib txoj hauv kev tsim kho tib neeg kom nkag siab txog qhov xav tau dej tiag tiag uas txawv ntawm ib tus neeg mus rau ib tus neeg, xws li tus nqi ntws, kev lag luam, thiab tus cwj pwm dej. Txawm hais tias tus nqi ntws zoo los yog phem muaj ntau yam ua rau cov cwj pwm dej. Nws tsis raug kho kom sib npaug, tab sis faib raws li kev xav tau. Koj yuav tsum xav txog txhua qhov dej tawm.
3. Hais txog phab ntsa thickness
Rau cov kav dej uas muaj tib txoj kab nruab nrab sab nraud, qhov nyias nyias ntawm phab ntsa thickness, lub puab txoj kab uas hla yuav loj dua me ntsis, tab sis qhov no yog tus nqi ntawm cov phab ntsa nyias nyias. Cov phab ntsa thickness cuam tshuam li cas? Nws yog lub siab muaj peev xwm ntawm cov kav dej thiab lub neej kev pab cuam ntawm cov kav dej. Thiab qhov dej ntws ntawm peb cov kav dej yog dab tsi? Raws li peb tau hais los saum no, tus nqi ntws ntawm cov kav dej feem ntau yog nyob ntawm txoj kab uas hla ntawm cov yeeb nkab. Qhov sib txawv ntawm cov yeeb nkab txoj kab uas hla yog feem ntau nyob rau hauv qhov kev txiav txim ntawm millimeters, thaum qhov sib txawv ntawm phab ntsa thickness yog nyob rau hauv millimeter tom ntej.
4. Hais txog lub teeb kis tau tus mob
Vim li cas peb ntxiv xim masterbatch thaum peb tsim cov kav dej, vim li cas ho tsis ua kom lawv pob tshab? Qhov no yog qhov ua tau kom cov kav dej opaque, yog li nws yuav tsum tau ntxiv cov xim masterbatches rau cov kav dej. Vim tias lub teeb tawm mus rau hauv dej los ntawm cov yeeb nkab dej, nws yuav ua rau cov algae loj hlob ntawm phab ntsa ntawm cov yeeb nkab dej, uas tsis tsim nyog rau kev siv thiab tu cov kav dej.
Tom qab ntawd vim li cas qee cov kav dej muaj xim nrog cov xim masterbatches tseem pob tshab? Qhov no yog vim cov xim masterbatches lawv siv tsis txaus npog lub hwj chim. Cov kav dej zoo tiag tiag yuav tsum tsis muaj opaque.
5. Txog cov khoom siv raw
Qhov sib txawv ntawm cov khoom siv raw zoo thiab cov khoom siv tsis zoo yog tias cov khoom siv tsis zoo muaj qhov dav melting ntau thiab ntau dua yaj ntws. Cov teeb meem no yuav ua li cas? Ntawd yog, cov yeeb nkab dej pib yaj ntawm qhov kub qis thaum lub sij hawm vuam, thiab cov khoom yuav thinner thiab softer tom qab melting. Cov khoom uas nyias nyias thiab mos yog qhov tseeb tsis haum rau vuam, thiab cov welded yeeb nkab yog yooj yim dua ib yam dab tsi mus tsis ncaj ncees lawm. Tom qab ntawd vim li cas qhov tshwm sim no tshwm sim nrog cov khoom tsis zoo? Yooj yim muab, nws yog vim muaj ntau yam khoom sib xyaw hauv cov khoom. Tom qab muaj ntau yam sib xyaw, qhov pib melting feem ntau yuav txo qis thiab cov melting ntau yuav elongate.
IFAN's ppr khoom yog cov yam ntxwv zoo, txais tos kom xaj.
