Intshayelelo:I-arhente yokugqiba ukugquma, ekwabizwa ngokuba yiglue yokwambathisa, luhlobo lwekhompawundi yepolymer egqunywe ngokulinganayo kumphezulu welaphu.Yenza enye okanye ngaphezulu kweengqimba zefilimu kumphezulu wengubo ngokubambelela, okungenakuphucula kuphela ukubonakala kunye nesitayela sendwangu, kodwa nokwandisa umsebenzi wendwangu, ukwenzela ukuba ilaphu linemisebenzi ekhethekileyo efana nokuchasana kwamanzi. , ukunganyangeki koxinzelelo lwamanzi, ukungena komoya kunye nokungena kwamanzi, ukutshatyalaliswa komlilo kunye nokuthintela ukungcola, ukukhuselwa kokukhanya kunye nokubonakalisa.
Imbali yophuhliso
Ngaphezu kweminyaka engama-2000 eyadlulayo
Kwi-China yamandulo, i-glue yokugqoka yayisele isetyenziswe phezu kweendwangu.Ngelo xesha, yayiyizinto ezininzi zendalo ezifana ne-lacquer kunye neoli ye-tung, eyayisetyenziselwa ukuveliswa kwendwangu engenamanzi.
mihla
Iindidi ezahlukeneyo zokuncamathelisa zokwenziwa kwepolymer ezinomsebenzi ogqwesileyo ziye zavela.Imveliso yokuqala yayinesiphene sokungangeni manzi kuphela kodwa ingangeni kumanzi.Ilaphu eligqunyiweyo lalivakala lixinene kwaye lishushu xa lisetyenziswa, kwaye ubutofotofo balo babukwimeko embi.
Ukususela ngo-1970
Abaphandi baye baphuhlisa uthotho lwezinto zokuncamathelisa zokugquma kwamanzi kunye nokufuma okungenwa kukufuma kumalaphu ngokuguqula ubume bemichiza yezinto ezincamathelayo zokuncamathelisa kunye nokutshintsha iindlela zokulungisa ukutyabeka.
Kule minyaka yangoku
Izinto zokuncamathelisa ezisebenzayo kunye nezinto zokuncamathelisa ezidityanisiweyo nazo zenze inkqubela enkulu
Ukuhlelwa ngokwesakhiwo sekhemikhali
1. I-Polyacrylate (PA):
Ikwabizwa ngokuba yi-AC yokuncamathelisa, yeyona nto ixhaphakileyo kwaye ixhaphakile ngoku.Emva kokugquma, inokunyusa ukuva kwesandla, i-windproof kunye ne-sag.
I-PA emhlophe yokugubungela iglue, oko kukuthi, ukugquma i-resin emhlophe ye-acrylic phezu kwelaphu, inokunyusa ukugquma kwelaphu, iyenze i-opaque, kwaye yenza umbala welaphu ukhanye ngakumbi.
I-PA iglue yesilivere yokugquma, oko kukuthi, umaleko weglue emhlophe yesilivere igqunywe kumphezulu welaphu, ukuze ilaphu linomsebenzi wokukhusela ukukhanya kunye nemitha.Ngokuqhelekileyo isetyenziselwa amakhethini, iintente kunye nempahla.
2. Ipolyurethane (PU):
Emva kokugquma, ilaphu liziva ligcwele kwaye li-elastic, kwaye umphezulu unemvakalelo yefilimu.
I-Pu white glue yokugquma, oko kukuthi, umaleko we-polyurethane resin emhlophe igqunywe kumphezulu welaphu, kwaye umsebenzi wayo ngokusisiseko uyafana nowe-PA iglu emhlophe, kodwa i-Pu white glue yokugquma inovakalelo olugcweleyo, ukuqina ngakumbi. kunye nokukhawuleza okungcono.
I-Pu yesilivere yokugquma iglu inomsebenzi osisiseko ofanayo nowe-PA weglue yesilivere.Nangona kunjalo, ilaphu eligqunywe ngesilivere yePu linokuqina okungcono kunye nokukhawuleza okungcono.Kwiintente kunye namanye amalaphu afuna uxinzelelo oluphezulu lwamanzi, ilaphu lesilivere elakhiwe ngePu lingcono kune-PA elaphu eligqunywe ngesilivere.
3.Ipolyvinyl chloride (PVC):
Yenziwe ngelaphu lefiber yeglasi, ilaphu lomqhaphu leglasi kunye nelaphu lefiber yekhemikhali kwaye ligqunywe ngenkqubo ekhethekileyo.Ezona mpawu ziphambili zokwenziwa kwayo zezi: ukungangeni kwamanzi, ukunqanda ilangatye, ukungenwa kokungunda, ubungqina bokubanda kunye nobungqina bokuhlwa (kubhekiselwa kubo "njengelaphu elinobungqina obuthathu" kunye "nelaphu elinobungqina obuhlanu");Ukumelana nokuguga;ukukhuselwa kwe-UV;Ukucoca kulula;Ukumelana nobushushu obuphezulu (180 ℃) kunye nokugqunyelelwa kakuhle kwe-thermal.
4. I-Silicone:
I-silicone yokwambathisa okuphezulu, okwabizwa ngokuba yi-paper coating.Umqhaphu obhityileyo ulungele kakhulu ukwenza ilaphu lehempe.Ivakala igcwele, inkenekene kwaye ilastiki, inokomelela olomeleleyo kunye nokumelana nemibimbi.Kwilaphu elishinyeneyo, ino-elasticity elungileyo kunye nokukhawuleza.
5. Irabha yokwenziwa (njenge-neoprene).
Ukongezelela, kukho i-polytetrafluoroethylene, i-polyamide, i-polyester, i-polyethylene, i-polypropylene kunye neeprotheni.
Okwangoku, iipolyacrylates kunye ne-polyurethanes zisetyenziswa kakhulu.
