Mu ntchito zomanga ndi uinjiniya, kufunika kwa zomangira zolumikizirana sikunganyalanyazidwe kwambiri. Zipangizozi zimagwira ntchito yofunika kwambiri pakutsimikizira umphumphu ndi kukhalitsa kwa nyumba mwa kutseka mipata ndikuletsa kulowa kwa madzi, mpweya, ndi zinthu zina zovulaza. Pakati pa mitundu yosiyanasiyana ya zomangira zolumikizirana zomwe zilipo, chomangira cholumikizira cholumikizira cholumikizira cholumikizira chodziyimira pawokha chakhala chisankho chodziwika bwino chifukwa cha mawonekedwe ake apadera komanso ntchito zake zosiyanasiyana. Nkhaniyi ikufuna kufufuza makhalidwe, ubwino, ndi ntchito za chomangira cholumikizira ...
Chotsekera cholumikizira cha PU chodziyimira payokhaNdi chinthu chimodzi chopangidwa ndi polyurethane chomwe chimasonyeza kuyenda bwino komanso kudzikweza. Chimapangidwa ndi kuphatikiza kwa polyol ndi isocyanate, zomwe, zikasakanizidwa, zimakumana ndi mankhwala kuti apange sealant yolimba komanso yosinthasintha. Kudzikweza kwa sealant iyi kumalola kuti ifalikire mofanana komanso bwino pamwamba pa malo opingasa, kuonetsetsa kuti imamatira bwino komanso mofanana.
Kutanuka kwa sealant ndi khalidwe lina lofunika kwambiri lomwe limasiyanitsa. Lili ndi kusinthasintha kwabwino kwambiri ndipo limatha kupirira mayendedwe akuluakulu a mafupa chifukwa cha kusinthasintha kwa kutentha, kukhazikika kwa kapangidwe kake, kapena kugwedezeka. Kapangidwe kameneka kamatsimikizira kuti sealant imakhalabe yolimba ngakhale pansi pa mikhalidwe yosinthasintha, kuchepetsa chiopsezo cha kulephera kwa mafupa ndi kuwonongeka kwa kapangidwe kake.
Ubwino:
Self-leveling PU elastic joint sealant imapereka ubwino wambiri kuposa mitundu ina ya ma joint sealant. Choyamba, kudzikweza kwake kumachotsa kufunikira kwa zida kapena njira zina kuti zitheke bwino. Izi sizimangopulumutsa nthawi ndi khama komanso zimathandizira kuti ziwonekere bwino pa ma joints otsekedwa.
Kuphatikiza apo, kusinthasintha kwapadera kwa sealant iyi kumailola kuti igwirizane ndi mayendedwe a mafupa popanda kusweka kapena kung'ambika. Kusinthasintha kumeneku n'kopindulitsa makamaka m'nyumba zomwe zimasinthasintha kutentha kapena katundu wolemera. Kutha kupirira nyengo yosinthasintha kumawonjezera kulimba ndi moyo wautali wa mafupa otsekedwa, kuchepetsa kufunikira kokonza kapena kukonza pafupipafupi.
Kuphatikiza apo, chosindikizira cha PU chokhazikika chomwe chimakhazikika chimamatira bwino kwambiri pazinthu zosiyanasiyana, kuphatikizapo konkriti, chitsulo, matabwa, ndi pulasitiki. Kusinthasintha kumeneku kumapangitsa kuti chigwiritsidwe ntchito mosiyanasiyana, monga zolumikizira zowonjezera, zolumikizira zowongolera, ndi kutseka kwa perimeter. Kugwirizana kwa chosindikizira ndi zipangizo zosiyanasiyana kumatsimikizira mgwirizano wotetezeka komanso kutseka kogwira mtima, zomwe zimapangitsa kuti kapangidwe kake kagwire ntchito bwino.
Mapulogalamu:
Chotsekera cha PU chokhazikika chomwe chimagwiritsidwa ntchito kwambiri pa ntchito zambiri zomanga ndi zomangamanga. Chimagwiritsidwa ntchito kwambiri m'nyumba zamalonda ndi nyumba zogona, milatho, misewu ikuluikulu, mabwalo a ndege, ndi mafakitale. Ntchito zina zapadera ndi izi:
1. Ma Joints Okulitsa:
Chotsekera cha PU chokhazikika chomwe chimatsekeka bwino ndi chabwino kwambiri potsekera malo olumikizirana omwe ali m'nyumba za konkriti. Malo olumikizirana awa amaloleza kuyenda kwachilengedwe kwa nyumbayo chifukwa cha kusintha kwa kutentha kapena kukhazikika. Kutanuka kwa chotsekeracho kumalola kuti chikule ndikuchepa ndi malo olumikizirana, kuletsa madzi kulowa ndikusunga mawonekedwe ake.
2. Zolumikizira Zowongolera:
Zolumikizira zowongolera zimapangidwa mwadala mu simenti kuti zithetse ming'alu yomwe imachitika chifukwa cha kuchepa kwa chitsulo. Chotsekera cholumikizira cha PU chokhazikika chimatseka bwino zolumikizirazi, kuletsa kulowa kwa chinyezi, mankhwala, ndi zinyalala. Zimathandizanso kusunga malo osalala komanso ofanana, ndikuwonjezera kukongola kwa kapangidwe kake.
3. Kutseka kwa Mzere:
Chotsekeracho chimagwiritsidwa ntchito kwambiri potsekera mawindo, zitseko, ndi malo ena otseguka. Makhalidwe ake abwino kwambiri omatirira amatsimikizira kuti chitsekocho sichilowa madzi komanso sichilowa mpweya, kuteteza kutaya mphamvu ndikuwonjezera kugwiritsa ntchito mphamvu bwino kwa nyumbayo.
Chotsekera cha PU chokhazikika chomwe chimatha kusinthasintha chimapereka zabwino zambiri zomwe zimapangitsa kuti chikhale chisankho chabwino kwambiri pa ntchito zosiyanasiyana zomanga ndi zomangamanga. Mphamvu zake zodzikweza, kusinthasintha, ndi kulimba zimathandiza kuti malo olumikizirana otsekedwa akhale olimba, ogwira ntchito, komanso okongola. Pamene makampani omanga akupitilizabe kusintha, kufunikira kwa chotsekera cha PU chokhazikika chomwe chimatha kusinthasintha chikuyembekezeka kukula, chifukwa cha magwiridwe antchito ake apamwamba komanso kusinthasintha kwake.
