Polyurethane sealant. Hauj lwm. kheej ntawm daim ntawv thov

Ib-tivthaiv polyurethane sealant feem ntau thov yog tias tsim nyog ib yam dab tsi staple, kua nplaum, kev sib khi hlau, ceramics, cib, ua vaj tse thiab lwm tus neeg. Cov sib tov yog ib tug zoo compound muaj ib tug high degree ntawm kuj mus xeb, thiab ua ntau check thaum raug dej. Feem ntau thov sealant rau tsev ntoo.

Tom qab daim ntawv thov ntawm cov khoom siv rau saum npoo nws tej zaum yuav raug mus rau ntau yam kev ua, nrog rau cov xim muaj hlau thiab cov kua roj vanish. Polyurethane sealant adheres rau qhov chaw ceev txaus. Nyob rau hauv no hais txog, cov ua hauj lwm nrog rau cov khoom yuav tsum tau ua nyob rau hauv view ntawm lub chaw lub sij hawm. Nws yuav tsum tau muab sau tseg hais tias kev siv ntawm cov khoom yuav tsum tau ua raws li tej yam muaj kev ruaj ntseg cov kev cai. yuav tsum tsis txhob sib cuag nrog lub sib tov thiab raug daim tawv nqaij. Polyurethane sealant los nyob rau hauv ib tug kaw pob. Material yuav tsum tsis txhob muab cia rau hauv ib tug txhawb kub thiab humidity. Qhov nruab nrab lub txee lub neej ntawm tsis tau qheb pob yog kwv yees li cuaj lub hlis. Ntaub ntawv los ntawm lub qhib pob yog ntshaw kom siv tam sim ntawd, raws li cov polyurethane nplaum sai sai loses nws pab zog.

Qhov no cov ntaub ntawv uas yog ib tug homogeneous khov loj tsim ntawm cob. Los ntawm reacting nrog dej muaj nyob rau hauv cov huab cua, muaj ib tug compound ntawm polymerization.

Daim ntawv thov nta ntawm cov ntaub ntawv uas yog txiav txim los ntawm nws cov hauj lwm yam ntxwv. Ntawm cov ntsiab qualities yuav tsum tau muab sau tseg nyob rau hauv daim ntawv thov ntawm tus nqi-cov hauj lwm zoo, tsis muaj shrinkage, daim ntawv thov adaptability, luv luv lub sij hawm ntawm hardening. Attendance tseem ceeb yog cov nplaum zog thiab elasticity ntawm lub dag lub zog, durability, maintainability. Polyurethane sealant yuav tsum muaj ntaub ntawv ntawm txaus tsawg kub.

Cov kev ua tau thaj chaw ntawm cov ntaub ntawv uas pub rau thov nws qhov txhia chaw. Tshwj xeeb tshaj yog polyurethane sealant lug siv nyob rau hauv kev tsim kho rau tus rwb thaiv tsev pob qij txha ntawm insulating iav, thaum da dej waterproofing, vov tsev ntaus ntawv. Nyob rau hauv raws li txoj kev ntawm kev siv cov ntaub ntawv uas yuav tsum tawm nyob rau hauv ob hom.

Nyob rau tej qhov chaw cov ntaub ntawv uas yog thov raws li ib tug kua mastic. Yog li tsim rau ntawm qhov chaw heev check waterproof membrane uas yog resistant rau kev phiv tej yam: kab mob, ultraviolet thiab lwm yam.

Ntau khov sealant yog thov sau nqaws, pob qij txha, thiab sealing feem rau cov tebchaw los yog lwm yam ntaub ntawv. lub compositions yog siv nquag thiab kev koom ntaub ntawv muaj qhov sib txawv nyob rau hauv lub cev zog.

Lub ntsiab qhia thaum xaiv ib sealant yog nws hardness. Lub hardness nyob rau hauv cov ntaub ntawv no yog cov muaj peev xwm mus tiv thaiv lub nkag mus ntawm tus lwm yam ntaub ntawv. Yog li, lub sealant nrog lub Performance index 15 yog siv los cais lub-ru tsev pob qij txha, inter-vaj huam sib luag tej pob qij txha, txuas pob qij txha ntawm prefabricated lug. hardness theem 25 tso cai rau kom siv cov khoom siv rau lub rho tawm cov pob qij txha uas thaum lub sij hawm ib tug ntev lub sij hawm yuav nyob ntawm dej.
