Pulp molded rooj tog yog muab faib ua ob pawg
1. Raws li qhov yuav tsum tau ua ntawm craftsmanship, ncaj qha pwm rau hauv tej yam yooj yim rooj tog.
2. Kev sib dhos ntawm cov khoom siv rooj tog molded raug tshem tawm tom qab cov khoom sib txuas, thiab kev ua haujlwm ntawm cov rooj tog zaum tiav.
Raw khoom configuration: Moulded rooj tog feem ntau siv cov ntawv pov tseg thiab khib nyiab cardboard ua raw khoom. Cov ntawv xov xwm, cov ntawv xov xwm, cov phau ntawv, ntau cov ntawv ntim khoom, ntawv ua haujlwm, ntawv tshaj tawm, ntawv thawv ntawv, thiab lwm yam yog txhua yam khoom siv raw. Cov ntaub ntawv raw yog raug ntaus nrog dej, thiab tom qab ntawd cov pulp, auxiliaries, additives, thiab lwm yam yog tov nyob rau hauv ib qho kev faib ua feem thiab ces ua tiav los ntawm deletion, xaiv, purification, thiab lwm yam, thiab tov rau hauv ib tug ntshiab pulp nrog ib tug tej yam concentration.
Cov txheej txheem khiav: khib nyiab sorting → pulping → purification → sizing → slurry kua nplaum npaj → siab sib sau → dehydration → monotonous → rooj tog zaum
1. Cov tshuaj ntxiv. Thaum lub sij hawm noj cov khoom siv ntawm cov khoom siv rooj tog zaum, ntxiv cov khoom tsim nyog ntawm cov khoom siv ntxiv raws li cov khoom siv uas xav tau los ntawm cov rooj tog zaum, thiab tsim cov pob txha txhawb nqa tsim nyog. Cov additives yog:
2. Tus neeg sawv cev ntxiv dag zog txhim kho lub zog thiab flexural lub zog ntawm cov khoom, kom lub zog thiab tensile quab yuam ntawm cov khoom tau zoo dua, cov khoom siv lub cev tau txhim kho, thiab cov flatness kuj tseem txhim kho.
3. Lub colloid ua rau cov khoom tawv thiab tsis ntsws los yog deform, thiab txhim kho cov dej tsis kam ntawm cov khoom.
4. Pigments, ntxiv cov xim xim raws li cov xim yuav tsum tau ua ntawm cov khoom.
5. Cov tshuaj tua kab, ua lub luag haujlwm tiv thaiv kab.
6. Elastic additives, nce elasticity ntawm qhov chaw.
Dab tsi yog cov tswv yim tsim ntawm pulp molded rooj tog?
1. Qhov zoo tshaj plaws ntawm pulp molding yog tias nws tsis tshua muaj kev cuam tshuam rau ib puag ncig, yog li nws feem ntau raug xaiv los ua cov khoom siv zoo tshaj plaws rau cov khoom zoo ib puag ncig.
2. Cov tawv nqaij tsis kho feem ntau muaj ob hom xim av thiab grey. Brown pulp feem ntau ua tiav los ntawm kraft ntawv. Grey pulp yog synthesized los ntawm recyclable printing ntawv. Hauv qhov sib piv, xim av pulp muaj lub zog zoo dua thiab rov zoo dua.
3. Pulp molded khoom yog nyob rau hauv daim ntawv ntawm nyias plhaub.
4. Cov khoom uas yog monotonously tsim nyob rau hauv cov huab cua yog lubricated ntawm ib sab (sab uas haum rau pwm), thiab lwm sab yog ntxhib, yog li cov khoom cov ntsiab lus feem ntau yog ntxiv rau ntawm tus du nto (sab uas haum rau pwm), xws li cov logos thiab cov lus piav qhia.
5. Cov txheej txheem ntub dej tuaj yeem txhim kho qhov zoo ntawm cov khoom pov tseg; thaum lub kub nias txoj kev txhim kho cov tsos zoo, nws yuav txo cov permeability ntawm cov khoom.
Ntsuab tsim thiab humanized tsim yog cov ntsiab lus ntawm cov rooj tog zaum tom ntej. Thaum siv cov ntawv pov tseg los tsim cov rooj tog molded, peb yuav tsum ua tib zoo xav txog qhov tsis zoo ntawm cov khoom siv ntawm cov khoom siv hauv cov txheej txheem los nrhiav qhov zoo thiab tsis txhob muaj qhov tsis zoo. Tiag tiag ua kom tiav cov qauv ntsuab thiab humanized tsim ntawm pulp molded rooj tog khoom.
