Ubwino wa zinthu umagwirizana mwachindunji ndi kusankha kwa zipangizo.Ubwino wa zipangizo zimadalira mtundu wa zipangizo ndi kuchuluka kwa zipangizo zomwe zawonjezeredwa.Choncho, popanga mtundu uliwonse wa zinthu, tiyenera kusamala posankha zipangizo.Ndi wopanga wamtundu uti yemwe amafunikira matumba a chidebe ambiri kuti apangidwe, ndiye mulingo wanji wosankha matumba a chidebe?Kodi tingapange bwanji matumba a chidebe ndi kuthamanga kwambiri?Xiaobian akufuna kugawana nanu ndikuwona.
Zida zazikulu zopangira matumba ndi polypropylene, calcium carbonate ndi anti-aging agents, zomwe zimadziwika ndi anti-aging agent: 3,5_Dimethoxy-4-hydroxybenzoic acid, 3,5_ Dimethoxy-4-hydroxybenzoic acid accounts 1- 5% ya kulemera konse kwa polypropylene.Calcium carbonate imapanga 5-10% ya kulemera konse kwa polypropylene, ndi UV absorber amawonjezeredwa ku 3,5-dimethoxy-4-hydroxybenzoic acid, ndipo UV absorber ndi o-hydroxybenzophenone.Pambuyo poyezetsa ukalamba, kusungitsa mphamvu yakusweka kwa warp ndi 70-75%, ndipo mphamvu ya weft ndi 55-60%.Chikwamacho chikapangidwa ndi calcium carbonate chokhala ndi 5-10% ya kulemera kwa polypropylene, chimakhala ndi kukana kukalamba bwino ndipo chitha kugwiritsidwa ntchito ngati zopangira zopangira matumba.Ndipo tisaiwale kuti matumba chidebe sayenera padzuwa kwa nthawi yaitali, kuti kupewa mosalekeza kuchepa kwa kumakoka mphamvu ya polypropylene mu matumba chidebe.
Kwa opanga matumba a chidebe, pokhapokha atapanga zinthu zabwino zamatumba a chidebe, angalimbikitse kupikisana kwawo pamsika.Popanga matumba a chidebe, sayenera kukhala osasamala pakugwiritsa ntchito zida zopangira ndi kukonza.Ndi njira iyi yokha yomwe angapangire matumba a chidebe oyenerera.
