Zovala zachikopa zofewa, siketi yachikopa yachikopa yopanda PU yachikopa yachikopa yachikopa ya sofa yachikopa chachikopa chikwama chofewa chobisika 0.6mm

Kufotokozera Kwachidule:

Zizindikiro zazikulu
1. Mphamvu yong'amba. Kung'ambika ndi chizindikiro chachikulu cha chikopa cha zovala, chomwe chimasonyeza kulimba kwa chikopa
2. Elongation pansi pa katundu. Kutalikirana pansi pa katundu kumawonetsa kulimba kwachikopa, nthawi zambiri kutalika kwa katundu wa 5N/mm2. Pazikopa zonse zomwe zimagwiritsidwa ntchito popanga zovala, kutalika kwa katundu kuyenera kukhala pakati pa 25% ndi 60%.
3. Kuthamanga kwamtundu kutikita. Kuthamanga kwamtundu pakupaka kumawonetsa kufulumira kwa utoto wachikopa, ndipo nthawi zambiri amayesedwa ndi zopaka zowuma 50 ndi zopaka 10 zonyowa pansi pa katundu wina. Pazikopa zonse zomwe zimagwiritsidwa ntchito popanga zovala, kupukuta kowuma kuyenera kukhala kokulirapo kuposa kapena kofanana ndi 3/4, ndipo kunyowa kumathamanga kuyenera kukhala kwakukulu kuposa kapena kofanana ndi 3/3.
4. Kuchita kwachitetezo. Chitetezo cha chikopa chimakhudza makamaka zizindikiro zachitetezo cha chilengedwe monga zitsulo zolemera, hexavalent chromium, formaldehyde, ndi utoto wonunkhira wa amine woletsedwa.
Malangizo ogula
1. Yang'anani pamanja ubwino wa chikopa. Chikopa chosawoneka bwino chikhoza kukhala ndi zolakwika monga kung'aluka, kusinthika, komanso kung'ambika pamwamba. Njira zotsatirazi zingagwiritsidwe ntchito kuzizindikira pogula:
Kung'amba: Kanikizani pamwamba pa chikopa ndi dzanja limodzi, tambasulani chikopa ndi dzanja lina, ndipo gwiritsani ntchito chala cholozera mmwamba kuchokera mkati mwa chikopacho. Ngati chophimbacho chikung'ambika, ndikusweka.
Kusintha kwamtundu: Gwiritsani ntchito nsalu yofewa yonyowa pang'ono kuti mupukute pachikopa mobwerezabwereza kwa 5 mpaka 10. Ngati nsalu yofewa yoyera imakhala yodetsedwa, ikhoza kuganiziridwa kuti chikopacho chimatayika.
Pang'onopang'ono: Pindani chosalala m'makona anayi ndikuchikanikiza mwamphamvu ndi manja anu. Ngati ming'alu ikuwoneka pamtunda wosalala, imatha kuonedwa ngati yosweka.
2. Kununkhiza fungo. Chikopa chenicheni nthawi zambiri chimakhala ndi fungo lodziwika bwino lamafuta, koma sichiyenera kukhala ndi fungo loyipa kapena loyipa. Ngati inu nokha mukuganiza kuti fungo la chovalacho ndi losavomerezeka, sikoyenera kugula.
3. Sankhani amalonda odziwika ndi mitundu. Ikani patsogolo kugula zovala zachikopa m'malo ogulitsira ambiri. Amalonda abwino ali ndi ulamuliro wokhwima pa khalidwe la katundu wogulidwa, ndipo mtundu wa zovala zomwe amagulitsa ndizotsimikizika bwino.
Ikani patsogolo kugula zinthu kuchokera kuzinthu zodziwika bwino. Makampani ambiri amtundu wamtunduwu ali ndi chidziwitso chochuluka pakukonza zovala ndi kasamalidwe koyenera, mikhalidwe yabwino yopangira ndi zida, kusankha mosamalitsa komanso kuwongolera bwino kwazinthu zopangira, ndipo makamaka palibe "zabodza".
4. Yang'anani chizindikiro. Yang'anani mosamalitsa dzina la fakitale, adilesi, chizindikiro, mawonekedwe, mtundu wazinthu, kapangidwe ka nsalu ndi zomwe zili, miyezo yoyendetsera, ndi satifiketi yogwirizana pacholemba.
