Pulp molding yog peb -papermaking technology. Nws siv cov ntawv pov tseg raws li cov khoom siv raw, thiab cov pwm tshwj xeeb yog siv los pwm ib yam khoom ntawm daim ntawv ntawm lub tshuab molding. Pulp molded cov khoom yog cov khoom ntim tshiab ceev hauv xyoo tas los no thiab hloov pauv zoo rau ntoo. Pulp molded cov khoom siv cov txheej txheem tsim khoom ntawm raw khoom ntaus-cov khoom xyaw- molding forming- ziab-shaping. Yog li dab tsi yog cov yam ntxwv ua haujlwm ntawm pulp molding?
Dab tsi yog cov yam ntxwv ua haujlwm ntawm pulp molding:
1. Cov khoom siv raw ntawm molded pulp ntim cov khoom yog cov ntawv pov tseg thiab ntau yam khoom siv fiber ntau ntawv mills. Nws muaj ntau qhov chaw thiab yooj yim los sau. Nws yuav tsis ua teeb meem rau ib puag ncig thiab rov ua dua tshiab, thiab muaj txiaj ntsig zoo rau kev xa tawm cov khoom. Raws li ua npuas ncauj plastics los ntawm cov khoom siv roj av, cov peev txheej depletion thiab nqi teeb meem yuav dhau los ua qhov hnyav dua.
2. Muaj thiab tiv thaiv cov khoom ntim khoom yog ib qho tseem ceeb ntawm cov khoom siv molded pulp. Moulded pulp cov khoom lag luam yuav tsum muaj peev xwm ntseeg tau cov khoom ntim tau teev tseg los ntawm kev ntim khoom, kom cov khoom ntim yuav tsis raug puas tsuaj thaum thauj, tuav, thiab siv, thiab ua tau raws li qhov yuav tsum tau muaj zog, nruj thiab ruaj khov ntawm nws tus kheej. Cov khoom siv hauv cov khoom siv molded pulp kuj muaj kev nyab xeeb rau cov khoom ntim, thiab tsis muaj kev cuam tshuam ntawm ob.
3. Nws yog ib qho yooj yim mus use, uas yog, cov qauv ntawm cov pulp molded khoom yuav tsum qab ntxiag. Cov qauv thiab cov duab ntawm cov khoom siv molded yuav tsum tsis txhob ua phem rau tib neeg lub cev, thiab hloov mus rau kev ua haujlwm thiab tuav ntawm tib neeg lub cev thaum siv.
4. Pulp molded cov khoom raug hloov kho kom ncua sij hawm sib xws thiab nqus cov zog sab nraud los ntawm lawv cov qauv tshwj xeeb thaum thauj khoom, kom txo tau qhov cuam tshuam thiab kev co ntawm cov khoom ntim. Nws txawv ntawm lub cushioning mechanism ntawm foam yas ntim khoom, vim hais tias cov khoom ua npuas ncauj muaj ib tug loj tus naj npawb ntawm compressible hlwb faib nyob rau hauv cov khoom, tsis hais seb cov khoom zoo li cas, nws muaj zoo cushioning kev ua tau zoo, yog hais tias daim ntawv pulp yas zaj duab xis cov ntaub ntawv thiab Foam plastics yog tsim rau hauv lub dav hlau loj. Obviously, tus qub tuaj yeem cushioned, thaum lub tom kawg tsis tuaj yeem cushioned. Yog li ntawd, rau pulp- cov khoom siv yas zaj duab xis, kev tsim qauv zoo yog ua kom tiav kev tiv thaiv cov ntsiab lus thiab txhim kho nws thaum thauj thiab tuav. Qhov yooj yim guarantee ntawm kev poob siab absorbing peev.
5. Pulp molded ntim khoom muaj ntau yam kev siv. Tam sim no ua npuas ncauj yog siv los ua cov khoom siv hauv ob sab phlu. Yeej, cov khoom siv pulp molded tuaj yeem siv tau. Pulp molded cov khoom tuaj yeem muab ntim thiab khaws cia hauv pawg. Piv nrog cov yas foamed, nws nyob 1/2-2/5 tsawg qhov chaw cia thiab muaj nqi tsheb thauj mus los thiab khaws cia.
