Umehluko phakathi kwamanzi e-polyurethane ne-polyurethane esekelwe
I-Polyurethane engangenisi elisekelwe emanzini i-Polyurethane materproof coatis iyinhlangano enobungane obuphakeme be-polymer ebalaleleke nge-adhesion enhle nokunamathela okuhle. Inokunamathelisa okuhle kuma-substrates asuselwa ku-monce anjengokhonkolo kanye namatshe kanye nemikhiqizo yensimbi. Umkhiqizo unezakhiwo zamakhemikhali ezinzile futhi ungamelana nokuchayeka isikhathi eside elangeni. Inezici zobungqabavu obuhle nobukhulu obukhulu.
Izici Zokusebenza Komkhiqizo
1. Ukubukeka: Umkhiqizo kufanele ube mahhala kusuka ku-limps ngemuva kokuvusa nakwisimo somfaniswano.
2. Inamandla aphezulu ashubile, ukunwebeka okuphezulu, ukuqina okuhle, ukusebenza okuhle kumazinga okushisa aphezulu futhi aphansi, nokuguquguquka okuhle kokugqwayiza, ukuqhekeka, kanye nokodonga lwe-substrate.
3. Ukunamathela kwayo kuhle, futhi akukho ukwelashwa okuphambili okudingekayo kuma-substrates ahlukahlukene ahlangabezana nezidingo.
4. I-coating yomile futhi yakha ifilimu emva kwalokho kungukuthi kungukuphi okuvimbelani kwamanzi, ukuqinisa amandla, nokungamelana nokubumba nokukhathala.
I-5. Ukusebenza kwalo kwezemvelo kuhle, ngoba aqukethe izingxenye ze-benzene noma amalahle, futhi akukho solvent eyengeziwe edingekayo ngenkathi kwakhiwa.
I-6. Kungumkhiqizo oyedwa, osebenza okubandayo okulula ukuyisebenzisa futhi usebenzise.
Ububanzi besicelo somkhiqizo
1. Ilungele amakamelo angaphansi komhlaba, izindawo zokupaka ezingaphansi komhlaba, isitimela esivulekile kanye nemihubhe

3. Ukufaka amanzi okumanzi okuthe mpo nokufakwa emanzini okungamanzi kwamakhona okungamampunge, amalunga neminye imininingwane emihle, kanye nokubekwa uphawu kwamalunga angenamanzi.
4. Ukuvimbela amanzi amachibi okubhukuda, imithombo yokufakelwa, amathangi amanzi, neziteshi zokunisela.
I-5. Ukungena ngaphansi kwamanzi ezindaweni zokupaka kanye nophahla lwesikwele.
I-Polyurethane esuselwa ku-polyurethane materproof coatiof iyinhlanganisela ephezulu yama-materproof materproof ebiwomile futhi iqina ebusweni. Kwenziwe ama-isocyanates kanye nama-polyols njengezinto eziphambili zokwakha, anama-ejenti ahlukahlukene asizinda ahlanganisa ama-hardeners ahlanganayo namapulasitiki, futhi akhiqizwa yinqubo ekhethekile yokushisa kwama-deshydration aphezulu kanye ne-polymerization. Lapho isetshenziswa, isetshenziswa engxenyeni engaphansi yamanzi, kanye nefilimu elingenamanzi, eliguquguqukayo futhi selemthungo engenamanzi elingenamanzi le-polyurethane liyakhiwa endaweni yamakhemikhali ngokusabela kwamakhemikhali phakathi kwe-polyurethane prepolymer kanye nomswakama osemoyeni.
Izici Zokusebenza Komkhiqizo
1. Ukubukeka: Umkhiqizo ungumzimba ofana nomugqa ofanayo ngaphandle kwejeli nezigaxa.
2. Ingxenye eyodwa, ukulungele ukusetshenziswa esizeni, ukwakhiwa okubandayo, okulula ukuyisebenzisa, kanye nesidingo sokuqukethwe komswakama kwe-substrate akusiqili.
3. Ukunamathela okuqinile: Ukunamathela okuhle kokhonkolo, udaka, ubumbahelekile, udaka, izinkuni, njll. Izinto zokwakha, ukuguquguquka okuhle, ukuqhekeka okuningana nokuguquguquka nokuguquguquka kwe-substrate.
I-4. Ifilimu ngaphandle kwe-seams: Adhesion amahle, asikho isidingo sokusebenzisa i-primer kuma-substrates ahlukahlukene ahlangabezana nezidingo.

6 Ububanzi besicelo somkhiqizo
Ukuhlanganiswa kwamanzi okususelwa ku-polyurethane okususelwa ku-polyurethane kungasetshenziselwa ukwakhiwa kwamanzi amasha ezakhiwo ezintsha nezindala, izindlu zokugezela, amakamelo okugeza, amachibi okubhukuda, amaphrojekthi wokuvikela umphakathi, njll. Kungase futhi kusetshenziselwe ukwakhiwa okungangeni kwamapayipi wensimbi.
Umehluko phakathi kwe-polyurethane esekelwe kuwoyela kanye ne-polyurethane esekwe emanzini:
I-polyurethane esekelwe e-oyili inokuqukethwe okuqinile okuphezulu kunama-polyurethane asuselwa emanzini, kepha kwenziwa nge-isocyatate, ama-polyther, kanye nama-ejenti ahlukile ashubile ahlanganiswe namazinga okushisa ahlanganisiwe, njengokususwa kwamanzi nokusabela kwamanzi kanye nokusabela kwamanzi kanye nokusabela kwamanzi kanye nokusabela kwamanzi kanye ne-polymerization. Inezinhlamvu eziningi kakhulu zokungcoliswa, ngokuqhathaniswa ne-polyurethane esekelwe emanzini, okuwumkhiqizo ohlaza okotshani futhi onobungane bemvelo ngaphandle kokungcola. Ilungele ukusetshenziswa kwangaphakathi, njengamakhishi nezindlu zokugezela.
