Magwiridwe ndi mawonekedwe a pepala lachimbudzi ndi mapepala a malata

Mapepala achimbudzi, omwe amadziwikanso kuti crepe toilet paper, amagwiritsidwa ntchito makamaka paumoyo wa anthu watsiku ndi tsiku ndipo ndi imodzi mwamapepala ofunikira kwambiri kwa anthu.Pofuna kufewetsa pepala lachimbudzi, kufewa kwa pepala lachimbudzi kumawonjezeka mwa kukwinya pepalalo pogwiritsa ntchito makina.Pali zida zambiri zopangira mapepala akuchimbudzi, zomwe zimagwiritsidwa ntchito kwambiri ndi thonje zamkati, zamkati zamatabwa, zamkati zaudzu, zamkati zamapepala ndi zina zotero.Palibe saizi yofunikira pamapepala akuchimbudzi.Ngati pepala lachimbudzi lamitundu lipangidwa, utoto wokonzedwa uyenera kuwonjezeredwa.Pepala lachimbudzi limadziwika ndi kuyamwa kwamadzi amphamvu, mabakiteriya otsika (chiwerengero chonse cha mabakiteriya pa gramu imodzi ya kulemera kwa pepala sikuyenera kupitirira 200-400, ndi mabakiteriya amtundu monga mabakiteriya a coliform saloledwa), pepalalo ndi lofewa, mofanana mu makulidwe. , palibe mabowo, ndi makwinya wogawana, Mtundu wosasinthasintha komanso zonyansa zochepa.Ngati mukupanga timapepala tating'ono ting'onoting'ono ta pepala lachimbudzi la zigawo ziwiri, malo obowola azikhala ofanana, ndipo mapiniwo akhale omveka bwino, othyoka mosavuta komanso owoneka bwino.

Pepala lopangidwa ndi corrugated base pepala ndi pepala lokhala ndi malata, lomwe limagwiritsidwa ntchito makamaka ngati wosanjikiza wapakati wamakatoni.Mapepala ambiri a malata amapangidwa ndi mpunga wa laimu ndi udzu wa tirigu, ndipo zomwe zimagwiritsidwa ntchito kwambiri ndi 160 g/m2, 180 g/m2, ndi 200 g/m2.Zofunikira pamapepala a malata ndi mawonekedwe a ulusi wofanana, makulidwe ofanana a mapepala, ndi mphamvu zina monga kuthamanga kwa mphete, kulimba kwamphamvu, ndi kukana kupindika.Simathyoka pokankhira pepala lamalata, ndipo imakhala ndi kukana kwamphamvu kwambiri.Ndipo khalani ndi kuuma kwabwino komanso kupuma bwino.Mtundu wa pepala ndi wonyezimira wachikasu, wosalala, ndipo chinyezi ndi choyenera.
