Ndi mitundu yanji ya ulusi yomwe imagwiritsidwa ntchito kwambiri mumatope a polima?

Kuonjezera ulusi mumatope a polima kuti muzitha kugwira bwino ntchito yamatope yakhala njira wamba komanso yotheka.Ulusi womwe amagwiritsidwa ntchito kwambiri ndi awa

Fiberglass yosamva alkali?

Ulusi wagalasi umapangidwa ndi kusungunuka kwa silicon dioxide, ma oxides okhala ndi aluminiyamu, calcium, boron ndi zinthu zina, ndi kachulukidwe kakang'ono kothandizira kukonza monga sodium okusayidi ndi potaziyamu okusayidi kukhala mipira yamagalasi, kenako kusungunula ndi kujambula mipira yagalasi mu crucible.Ulusi uliwonse wopangidwa kuchokera ku crucible umatchedwa monofilament, ndipo ma monofilaments onse opangidwa kuchokera ku crucible amasonkhanitsidwa mu ulusi waiwisi (tow) atadutsa mu thanki yoviika.Pambuyo podulidwa, imatha kugwiritsidwa ntchito mumatope a polima.

Mawonekedwe a ulusi wamagalasi ndi mphamvu yayikulu, modulus yotsika, elongation yayitali, kukulitsa kwa mzere wocheperako, komanso kutsika kwamafuta.Mphamvu yamakomedwe ya galasi CHIKWANGWANI kuposa mphamvu ya zipangizo zosiyanasiyana zitsulo (1010-1815 MPa).

Velen fiber?

Chigawo chachikulu cha vinylon ndi mowa wa polyvinyl, koma mowa wa vinyl ndi wosakhazikika.Nthawi zambiri, vinyl alcohol acetate (vinyl acetate) yokhala ndi magwiridwe antchito okhazikika imagwiritsidwa ntchito ngati monomer polima, kenako polyvinyl acetate yomwe imabwera ndi mowa kuti ipeze mowa wa polyvinyl.Silika akagwiritsidwa ntchito ndi formaldehyde, vinylon yosamva madzi otentha imatha kupezeka.Kutentha kosungunuka (225-230C) wa mowa wa polyvinyl ndi wapamwamba kuposa kutentha kwa kutentha (200-220C), motero amapota ndi njira yopota.

Vinylon ali ndi hygroscopicity yolimba ndipo ndi mitundu yambiri ya hygroscopic pakati pa ulusi wopangidwa, womwe uli pafupi ndi thonje (8%).Vinylon ndi wamphamvu pang'ono kuposa thonje komanso wamphamvu kwambiri kuposa ubweya.Kukana dzimbiri ndi kukana kuwala: insoluble ambiri organic zidulo, alcohols, esters ndi mafuta osungunulira nyali, si zosavuta kuumba, ndi kutaya mphamvu si lalikulu pamene kuwala kwa dzuwa.Choyipa ndichakuti kukana kwa madzi otentha sikokwanira komanso kukhazikika kwake ndi koyipa.

Acrylic fiber?

Amatanthawuza ulusi wopangidwa ndi kupota konyowa kapena kupota kowuma kopitilira 85% ya copolymer ya acrylonitrile ndi monomer yachiwiri ndi yachitatu.

Ulusi wa Acrylic umalimbana bwino ndi kuwala komanso kukana nyengo, womwe ndi wabwino kwambiri pakati pa ulusi wamba wamba.Ulusi wa acrylic ukakhala padzuwa kwa chaka chimodzi, mphamvu zake zimachepa ndi 20%.Ulusi wa Acrylic uli ndi kukhazikika kwamankhwala abwino, kukana kwa asidi, kukana kwa alkali ofooka, kukana kwa okosijeni komanso kukana kwa organic zosungunulira.Komabe, ulusi wa acrylic umasanduka wachikasu mu lye, ndipo ma macromolecules amasweka.Mapangidwe a quasi-crystalline a acrylic fiber amapanga fiber thermoelastic.Komanso, akiliriki CHIKWANGWANI ali wabwino kutentha kukana, palibe mildew, ndipo saopa tizilombo, koma ndi osauka kukana kuvala ndi osauka dimensional bata.

Ulusi wa polypropylene?

Ulusi wa polyolefin wopangidwa kuchokera ku stereoregular isotactic polypropylene polima posungunula.Kachulukidwe kachibale ndi kakang'ono kwambiri pakati pa ulusi wopangira, mphamvu zowuma ndi zonyowa ndizofanana, ndipo kukana kwa dzimbiri kwamankhwala ndikwabwino.Koma ukalamba wa dzuwa ndi wosauka.Pamene polypropylene mauna CHIKWANGWANI aikidwa mu matope, pa kusanganikirana ndondomeko matope, yopingasa kugwirizana pakati pa CHIKWANGWANI monofilaments kuwonongedwa ndi akusisita ndi kukangana kwa matope palokha, ndi CHIKWANGWANI monofilament kapena maukonde dongosolo mokwanira anatsegula, kotero. kuti muzindikire kuchuluka kwake Zotsatira za ulusi wambiri wa polypropylene wosakanikirana wosakanikirana mu konkire.

Ulusi wa nayiloni?

Polyamide, yomwe imadziwika kuti nayiloni, ndi liwu lodziwika bwino la utomoni wa thermoplastic wokhala ndi magulu a amide mobwerezabwereza-[NHCO]-pa tcheni chachikulu cha maselo.

Nayiloni imakhala ndi mphamvu zamakina apamwamba, malo ochepetsetsa kwambiri, kukana kutentha, kugundana kochepa, kukana kuvala, kudzipaka mafuta, kuyamwitsa ndikuchepetsa phokoso, kukana mafuta, kukana kufooka kwa asidi, kukana kwa alkali ndi zosungunulira zonse, kutchinjiriza kwamagetsi kwabwino, kumakhala ndi Self- zozimitsa, zopanda poizoni, zopanda fungo, kukana kwanyengo kwabwino, utoto wopanda utoto.Choyipa chake ndikuti chimakhala ndi mayamwidwe apamwamba amadzi, omwe amakhudza kukhazikika kwa mawonekedwe ndi mphamvu zamagetsi.Kulimbitsa kwa fiber kumatha kuchepetsa kuyamwa kwamadzi kwa utomoni, kotero kuti zitha kugwira ntchito pansi pa kutentha kwambiri komanso chinyezi chambiri.Nayiloni imalumikizana bwino kwambiri ndi ulusi wagalasi.

Polyethylene fiber?

Ulusi wa polyolefin wopota kuchokera ku mzere wa polyethylene (wolemera kwambiri polyethylene) posungunuka.Zomwe zidalipo ndi:

(1) Mphamvu za fiber ndi kutalika kwake zili pafupi ndi za polypropylene;

(2) Kutha kuyamwa chinyezi kumafanana ndi polypropylene, ndipo kuchuluka kwa chinyezi kumakhala ziro mumlengalenga wabwinobwino;

(3) Ili ndi katundu wokhazikika wamankhwala, kukana kwamankhwala abwino komanso kukana dzimbiri;

(4) Kutentha kwa kutentha kumakhala kosauka, koma kukana kutentha ndi chinyezi kuli bwino, malo ake osungunuka ndi 110-120 ° C, omwe ndi otsika kuposa ulusi wina, ndipo kukana mabowo osungunuka ndi osauka kwambiri;

(5) Ili ndi zotsekera bwino zamagetsi.Kukana kwa kuwala ndikosavuta, ndipo ndikosavuta kukalamba ndi kuwala kwa kuwala.

Aramid CHIKWANGWANI?

Unyolo waukulu wa macromolecule wa polima umapangidwa ndi mphete zonunkhira ndi zomangira za amide, ndipo osachepera 85% amagulu a amide amalumikizidwa mwachindunji ndi mphete zonunkhira;maatomu a nayitrogeni ndi magulu a carbonyl m'magulu a amide a gawo lililonse lobwerezabwereza amalumikizana mwachindunji ndi mphete zonunkhiritsa ulusi wa aramid.

Fiber ya Aramid ili ndi zida zabwino zamakina komanso zosunthika monga kulimba kwamphamvu kwambiri, kulimba kwamphamvu kwambiri, kachulukidwe kakang'ono, kuyamwa bwino kwamphamvu komanso kuyamwa modabwitsa, kukana kuvala, kukana kukhudzidwa, kukana kutopa, komanso kukhazikika kwa mawonekedwe.Chemical dzimbiri, kukana kutentha kwambiri, kukulitsa otsika, otsika matenthedwe madutsidwe, osayaka, osasungunuka ndi zina zabwino kwambiri matenthedwe katundu ndi katundu dielectric.

ulusi wamatabwa?

Wood CHIKWANGWANI amatanthauza minofu makina wopangidwa ndi lignified unakhuthala cell khoma ndi CHIKWANGWANI maenje abwino ngati mng'alu, ndipo ndi chimodzi mwa zigawo zikuluzikulu za xylem.

Wood fiber ndi ulusi wachilengedwe womwe umayamwa madzi ndipo susungunuka m'madzi.Ili ndi kusinthasintha kwakukulu komanso dispersibility.
