Sefa imapezeka mu zipangizo zopondera komanso zoyezera. Ndi gawo lofunika kwambiri pa kupondera ndi kuyezera. Tikasankha chophimba chogwedezeka, nthawi zambiri timasankha chophimba chomwe chingakwaniritse zosowa zathu zoyezera malinga ndi mtundu wa zinthu zomwe kasitomala akuziika komanso kukula kwa tinthu ta zinthu zoyezera. Ndiye kusiyana kwawo ndi kotani pa magwiridwe antchito, zipangizo ndi ntchito? Xiaobian wotsatira ndi aliyense amamvetsetsana pamodzi.

Chophimba cha polyurethane
tanthauzo:
Dzina lonse la polyurethane ndi polyurethane, lomwe ndi dzina lophatikizana la macromolecular compounds okhala ndi magulu a urethane obwerezabwereza (NHCOO) pa unyolo waukulu. Amapangidwa powonjezera organic diisocyanate kapena polyisocyanate ndi dihydroxy kapena polyhydroxy compound.
gwiritsani ntchito:
Zophimba za polyurethane ndi za zida zamigodi ndipo zimagwiritsidwa ntchito m'migodi ndi m'mabwalo a miyala pamodzi ndi zida zamigodi monga zophimba zogwedezeka.
Mawonekedwe:
Zipangizozi zili ndi mawonekedwe okongola, mtundu wowala, kulemera kopepuka, mphamvu yamakina yambiri, kutchinjiriza kutentha, kutchinjiriza phokoso, kukana dzimbiri, kukana nyengo yabwino kwambiri, kusakhala ndi zokongoletsera zina, komanso mitundu yosiyanasiyana. 1. Kukana kwabwino kwa kukanda komanso moyo wautali. Kukana kwake kukanda ndi kuwirikiza katatu mpaka kasanu kuposa mbale yachitsulo, komanso kuwirikiza kasanu kuposa mbale wamba ya rabara.
2. Ntchito yokonza ndi yochepa, sikirini ya polyurethane siiwonongeka mosavuta, ndipo nthawi yogwira ntchito ndi yayitali, kotero imatha kuchepetsa kwambiri kuchuluka kwa kukonza ndi kutayika kwa kupanga ndi kukonza.
3. Mtengo wonse ndi wotsika. Ngakhale kuti chophimba cha polyurethane cha mtundu womwewo (dera) chili ndi ndalama zokwana kamodzi (pafupifupi kawiri) kuposa chophimba cha chitsulo chosapanga dzimbiri, nthawi yogwiritsira ntchito chophimba cha polyurethane ndi nthawi 3 mpaka 5 kuposa chophimba cha chitsulo chosapanga dzimbiri. Chiwerengero cha nthawi ndi chochepa, kotero mtengo wonse si wokwera, ndipo ndi wotsika mtengo.
4. Kukana chinyezi bwino, kumatha kugwira ntchito ngati madzi ali ngati sing'anga, ndipo pankhani ya madzi, mafuta ndi zinthu zina, kuchuluka kwa kukangana pakati pa polyurethane ndi zinthu kumachepa, zomwe zimathandiza kwambiri kuti zitseguke bwino, kukonza magwiridwe antchito, komanso kupewa tinthu tonyowa. Nthawi yomweyo, kuchuluka kwa kukangana kumachepa, kuwonongeka kumachepa, ndipo moyo wautumiki umawonjezeka.
5, kukana dzimbiri, kosayaka moto, kopanda poizoni komanso kopanda kukoma.
6. Chifukwa cha kapangidwe koyenera ka mabowo a sefa ndi njira yapadera yopangira mbale ya sefa, tinthu tating'onoting'ono tomwe tili ndi malire ake sitidzatseka mabowo a sefa.
7, kuyamwa bwino kwa kugwedezeka, kuthekera kochotsa phokoso mwamphamvu, kumatha kuchepetsa phokoso, ndikupangitsa zinthu zomwe zili pa sefa kukhala zovuta kuswa panthawi yogwedezeka.
8. Chifukwa cha makhalidwe a kugwedezeka kwachiwiri kwa polyurethane, chophimba cha polyurethane chimadziyeretsa chokha, kotero mphamvu yowunikira ndi yayikulu.
9. Kusunga mphamvu ndi kugwiritsa ntchito pang'ono. Polyurethane ili ndi mphamvu yochepa yokoka ndipo ndi yopepuka kwambiri kuposa sefa yachitsulo yofanana, yomwe imachepetsa katundu pa chotchingira, kusunga mphamvu ndikuwonjezera moyo wa chotchingira.

Chophimba chachitsulo cha Manganese
Tanthauzo: Chophimba chachitsulo cha Manganese ndi chinthu chopangidwa ndi maukonde achitsulo chomwe chimagwiritsidwa ntchito poyesa ndi kusefa. Chingapangidwe kukhala chipangizo cholimba choyezera ndi kusefa cha mawonekedwe osiyanasiyana.
gwiritsani ntchito:
Amagwiritsidwa ntchito kwambiri pochotsa matope, kusefa, kuchotsa madzi m'nthaka, komanso kuchotsa matope m'mafakitale ambiri.
Mawonekedwe:
Mphamvu yayikulu, kuuma komanso mphamvu yonyamula katundu.
