Kuyesera kumeneku kumachitika potenga mtolo wa nsalu yokhala ndi ulusi wopindika ndi wopindika pa msoko wa chovalacho, kuuyatsa ndikuwona momwe lawi lilili, kununkhiza fungo lomwe limapangidwa panthawi yoyaka, ndikuyang'ana zotsalira pambuyo poyaka, kuti adziwe ngati kapangidwe ka nsalu komwe kakuwonetsedwa pa chizindikiro cholimba cha chovalacho ndi koona komanso kodalirika, potero kuzindikira ngati ndi nsalu yabodza.
1. Ulusi wa polyamideDzina la sayansi la nayiloni ndi polyester nayiloni, zomwe zimapindika mwachangu ndikusungunuka kukhala ulusi woyera wa gelatinous pafupi ndi lawi. Zimasungunuka ndikuyaka mu malawi ndi thovu. Palibe lawi likayaka. Popanda lawi, zimakhala zovuta kupitiriza kuyaka, ndipo zimatulutsa fungo la udzu winawake. Pambuyo pozizira, kusungunuka kofiirira pang'ono sikophweka kuswa. Ulusi wa polyester ndi wosavuta kuyaka ndikusungunuka pafupi ndi lawi. Mukayaka, umasungunuka ndikutulutsa utsi wakuda. Ndi malawi achikasu ndipo umatulutsa fungo. Phulusa likayaka ndi tinthu takuda tofiirira tomwe tingapotozedwe ndi zala.
2. Ulusi wa thonje ndi ulusi wa hemp, ikakhala pa malawi, yatsani nthawi yomweyo ndipo yatsani mwachangu, ndi lawi lachikasu ndi utsi wabuluu. Kusiyana pakati pawo kuli mu fungo: thonje limatulutsa fungo la pepala loyaka, pomwe hemp imatulutsa fungo la udzu woyaka kapena phulusa. Pambuyo poyaka, thonje limasiya zotsalira zochepa kwambiri, zomwe zimakhala zakuda kapena imvi, pomwe hemp imasiya phulusa loyera lopepuka.
3. Pameneubweya ndi ulusi wa ubweya wa silikaAkakumana ndi moto ndi utsi, pang'onopang'ono amatuluka ndi kupsa. Amatulutsa fungo la tsitsi loyaka. Phulusa lalikulu likapsa ndi tinthu takuda tonyezimira, tomwe timaphwanyidwa zala zikangokanidwa. Silika ikapsa, imachepa n’kukhala mpira ndipo imapsa pang'onopang'ono, limodzi ndi phokoso lofuula, kutulutsa fungo la tsitsi loyaka, kupsa n’kukhala phulusa laling'ono lofiirira, ndikupotoza manja kukhala zidutswa.
4. Ulusi wa acrylic ndi ulusi wa polypropylene acrylic amatchedwaulusi wa polyacrylonitrile. Amasungunuka ndi kuchepera pafupi ndi lawi, amatulutsa utsi wakuda akayaka, ndipo lawi limakhala loyera. Pambuyo pochoka pa lawi, lawi limayaka mwachangu, kutulutsa fungo lowawa la nyama yopsereza, ndipo phulusa ndi zipolopolo zakuda zolimba zosakhazikika, zomwe zimakhala zosavuta kupotoza ndikusweka ndi manja. Ulusi wa polypropylene, womwe umadziwika kuti ulusi wa polypropylene, umasungunuka pafupi ndi lawi, umayaka pang'onopang'ono, umayaka pang'onopang'ono komanso umatulutsa utsi, lawi lapamwamba ndi lachikasu, lawi la pansi ndi labuluu, ndipo limatulutsa fungo la utsi wa mafuta. Phulusa likayaka ndi tinthu tolimba tozungulira topepuka tachikasu-bulauni, tomwe timakhala tosavuta kusweka ndi manja.
5. Ulusi wa polyvinyl alcohol formaldehyde, yomwe imadziwika mwasayansi kuti vinylon ndi vinylon, siivuta kuyatsa, kusungunula ndi kufinya pafupi ndi moto. Ikayaka, pamakhala lawi loyatsira pamwamba. Ulusi ukasungunuka kukhala lawi lofanana ndi gelatinous, umakhala waukulu, umakhala ndi utsi wakuda wambiri, ndipo umatulutsa fungo lowawa. Pambuyo poyaka, pamakhala tinthu tating'onoting'ono takuda tomwe tingaphwanyidwe ndi zala. Ulusi wa polyvinyl chloride (PVC) ndi wovuta kuyatsa, ndipo umazima nthawi yomweyo moto utatha, ndi malawi achikasu ndi utsi wobiriwira-woyera kumapeto. Amatulutsa fungo lowawa kwambiri. Phulusa likayaka ndi mabuloko akuda-ofiirira osakhazikika, omwe si osavuta kuwapotoza ndi zala.
6. Ulusi wa polyurethane ndi ulusi wa fluoropolyurethane zimatchedwaulusi wa polyurethane. Amasungunuka ndi kupsa m'mphepete mwa moto. Akapsa, lawi limakhala labuluu. Akachoka pamoto, amapitiriza kusungunuka. Amatulutsa fungo loipa. Phulusa likapsa limakhala lofewa komanso lofewa lakuda. Ulusi wa Polytetrafluoroethylene (PTFE) umatchedwa ulusi wa fluorite ndi bungwe la ISO. Umasungunuka pafupi ndi lawi, ndi wovuta kuyatsa, ndipo sudzapsa. Lawi la m'mphepete ndi carbonization ya buluu-yobiriwira, kusungunuka, ndi kuwonongeka. Mpweyawo ndi woopsa, ndipo kusungunuka ndi mikanda yakuda yolimba. Mu makampani opanga nsalu, ulusi wa fluorocarbon nthawi zambiri umagwiritsidwa ntchito popanga ulusi wosokera.
7. Ulusi wa Viscose ndi ulusi wa cuprammonium Ulusi wa ViscoseZimayaka moto, zimayaka mwachangu, lawi la moto ndi lachikasu, zimatulutsa fungo la pepala loyaka, ndipo zikayaka, pamakhala phulusa laling'ono, timizere tosalala topindika, ndi ufa woyera wopepuka wa imvi kapena imvi. Ulusi wa Cuprammonium, womwe umadziwika kuti kapok, umayaka pafupi ndi lawi la moto. Umayaka mwachangu. Lawi la moto ndi lachikasu ndipo limatulutsa fungo la ester acid. Pambuyo poyaka, pamakhala phulusa laling'ono, phulusa laling'ono la imvi-yakuda.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri,chonde titumizireni
