Makampani opanga ma sandwich panel amadalira zipangizo zodzaza bwino zomwe zimapereka chitetezo, kukana moto komanso kukhazikika kwa kapangidwe kake.MXC-5, MXC-8, MXC-41) amagwira ntchito yofunika kwambiri popanga zinthuzi, zomwe zimathandiza kuti pakhale njira zogwirira ntchito mwachangu komanso moyenera popanga thovu. Zipangizo zomwe zimagwiritsidwa ntchito kwambiri mu sandwich core ndi zinthu zopanda chilengedwe monga polyurethane (PUR), polyisocyanurate (PIR), polystyrene, phenolic thovu (PF) ndi ubweya wa miyala. Pepalali limapereka chithunzithunzi cha zinthuzi ndi momwe ma polyurethane catalysts angathandizire kupanga ndi kugwiritsa ntchito kwawo m'ma sandwich panels.
Zipangizo Zodzaza Kawirikawiri za Ma Sandwich Panels
Zipangizo zomwe zimagwiritsidwa ntchito mu sandwich panel cores zitha kugawidwa m'magulu awiri akuluakulu: zipangizo zopangidwa ndi thovu ndi zinthu zopangidwa ndi ulusi wosapangidwa ndi organic. Mtundu uliwonse wa zinthu umakhala ndi mawonekedwe apadera omwe amaupangitsa kukhala woyenera kugwiritsidwa ntchito mwanjira inayake, kutengera zomwe gululo limafuna kutentha, kapangidwe kake, komanso kukana moto.
Zipangizo za Thovu
1. Polyurethane (PUR) ndi Polyisocyanurate (PIR):
Polyurethane (PUR) ndi polyisocyanurate (PIR) ndi zinthu ziwiri zomwe zimagwiritsidwa ntchito kwambiri popanga ma sandwich panels. Zipangizozi zimapangidwa ndi momwe ma polyol ndi isocyanates amagwirira ntchito ndi zinthu monga MXC-5,MXC-8, ndi MXC-41. Ntchito yothandizayi imatsimikizira kuti thovu limakula, limachira, komanso limalumikizana bwino mkati mwa kapangidwe ka mbale ya sandwich.
- Kumamatira ndi Kugwirizana kwa Kapangidwe:Chimodzi mwa zifukwa zazikulu zogwiritsira ntchito PUR/PIR m'ma sandwich panels ndi mphamvu zake zabwino kwambiri zomangira. Panthawi yogwiritsa ntchito thovu, PUR ndi PIR zimamatira bwino ku zinthu zapamwamba monga zikopa zachitsulo kapena aluminiyamu, motero zimawonjezera kulimba kwa kapangidwe ka gululo. Khalidweli limapangitsa kuti thovuli likhale losankha kwambiri pamizere yomatira, chifukwa chomangira cholimba ndikofunikira kuti likhale lolimba.
- Kulimbana ndi Moto Kwambiri:Kapangidwe ka mankhwala ka thovu la PUR/PIR kakhala kakusintha pakapita nthawi, komanso kukana moto, khalidwe lofunika kwambiri pa ntchito zomangira nyumba komwe malamulo okhwima oteteza moto ayenera kutsatiridwa. PIR, makamaka, imakhala ndi kukana moto bwino kuposa PUR, zomwe zimapangitsa kuti ikhale chisankho chachikulu pa ntchito zoopsa kwambiri.
2. Polystyrene (EPS/XPS):
Polystyrene, kuphatikizapo expanded polystyrene (EPS) ndi extruded polystyrene (XPS), ndi chinthu china cha thovu chomwe chimagwiritsidwa ntchito m'ma sandwich panels. Ngakhale sichigwiritsidwa ntchito kwambiri monga PUR/PIR, polystyrene imapereka mphamvu zabwino kwambiri zotetezera kutentha. Komabe, mphamvu zake zomatira sizolimba ngati PUR/PIR, kotero sizingakhale zoyenera kugwiritsa ntchito zomwe zimafuna mphamvu zambiri.
- Kuteteza kutentha:Polystyrene imapereka chitetezo chabwino kwambiri cha kutentha pamtengo wotsika poyerekeza ndi zipangizo zina, zomwe zimapangitsa kuti ikhale chisankho chodziwika bwino pamapulojekiti omwe amawononga ndalama zambiri. Komabe, ilibe mphamvu yolimbana ndi moto komanso yogwirizana ndi PUR ndi PIR.
3. Phenolic Thovu (PF):
Thovu la phenolic ndi latsopano poyerekeza ndi zinthu zina za thovu ndipo siligwiritsidwa ntchito kawirikawiri popanga masangweji. Komabe, limapereka ubwino umodzi wofunikira: kukana moto kwambiri. Thovu la phenolic lili ndi kukana moto kwabwino kwambiri pakati pa zinthu za thovu, zomwe zimapangitsa kuti likhale loyenera kugwiritsidwa ntchito pomwe chitetezo cha moto ndiye chinthu chofunikira kwambiri.
- Kukana Moto:Kapangidwe kake ka mankhwala ka thovu la phenolic kamathandiza kuti lipirire kutentha kwambiri popanda kuwononga kapangidwe kake. Ngakhale kuti limagwira bwino ntchito pamoto, thovu la phenolic siligwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wokwera komanso kupezeka kwake kochepa.
Zipangizo za Ulusi Wopanda Zachilengedwe
1. Ubweya wa Rock:
Ubweya wa Rockwool, womwe ndi ulusi wosapangidwa ndi zinthu zachilengedwe, umagwiritsidwa ntchito m'mabokosi a sandwich chifukwa cha kukana moto komanso mphamvu zake zoteteza mawu. Mosiyana ndi zinthu zopangidwa ndi thovu, ubweya wa rockwool suyaka, zomwe zimapangitsa kuti ukhale wabwino kwambiri pa ntchito zomwe zimayesedwa ndi moto.
- Kutentha ndi Kuteteza Phokoso:Rockwool imapereka chitetezo chothandiza cha kutentha, ngakhale kuti sichikhala chokwera ngati thovu lina. Kuphatikiza apo, kapangidwe kake ka ulusi kamathandiza kuchepetsa phokoso, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pofuna kuchepetsa phokoso.
- Kukana Moto:Ubwino waukulu wa Rockwool ndi kusayaka kwake. Imatha kupirira kutentha kwambiri, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri cha nyumba zomwe zimafuna chitetezo champhamvu pamoto.
Udindo wa Polyurethane Catalysts mu Kupanga Sandwich Panel
Ma catalyst a polyurethane monga MXC-5, MXC-8, ndi MXC-41 ndi ofunikira kwambiri pakupanga bwino zinthu za thovu zomwe zimagwiritsidwa ntchito m'ma sandwich panels. Ma catalyst awa amafulumizitsa machitidwe a mankhwala pakati pa ma polyol ndi isocyanates, kuonetsetsa kuti thovu limakula mofanana ndikuchira bwino. Popanda ma catalyst, yankho lingakhale lochedwa komanso losakwanira, zomwe zimapangitsa kuti thovu likhale losalimba komanso losakwanira kulumikiza komanso kuteteza.
- Kulamulira Kuyankha:Ma catalyst amawongolera kuchuluka kwa thovu lomwe limapanga, kuonetsetsa kuti thovulo likukulirakulira kuti lidzaze mkati mwa sandwich panel yonse. Amathandizanso kuti pakhale mgwirizano pakati pa kuphulika ndi kufalikira kwa ma gel, zomwe zimapangitsa kuti thovulo likhale lolimba komanso kapangidwe ka maselo.
- Zinthu Zofunika Kuganizira Pazachilengedwe:Ma catalyst ambiri amakono a polyurethane amapangidwira kuchepetsa kutulutsa kwa volatile organic compound (VOC) ndikuwonjezera chitetezo cha chilengedwe. Ma catalyst osanunkhira bwino komanso opanda mpweya, monga MXC-41, amathandizira kupanga ma sandwich panels abwino kwa chilengedwe.
Mapeto
Pakupanga mapanelo a sandwich, kusankha zinthu zoyenera kudzaza ndikofunikira kwambiri kuti zikwaniritse zofunikira pa kutentha, kapangidwe kake, komanso chitetezo cha moto. Zipangizo zopangidwa ndi thovu monga PUR, PIR, polystyrene, ndi phenolic thovu, pamodzi ndi zinthu zopanda chilengedwe monga rockwool, chilichonse chimakhala ndi ubwino wake wapadera. Zothandizira za polyurethane monga MXC-5, MXC-8, ndi MXC-41 zimathandiza kwambiri pakuonetsetsa kuti zinthu zopangira thovu zapamwamba zipangidwa bwino. Zothandizira izi zimathandizira kuti mankhwala a thovu azigwira ntchito bwino, zomwe zimapangitsa kuti thovu likhale lolimba, komanso kuti lisamavutike ndi moto zomwe ndizofunikira pa ntchito zamakono zomanga.
