Sealant: ya na ụdị na ojiji

Adhesives na sealants, nke na-n'ihu na ahịa taa bụ oké iche iche ma na-ji a sara mbara akporo ngwa.

Clay - a umi na a na-eji jikọọ dị iche iche ihe site a usoro nke adhesion n'etiti nyagide film dị iche iche na-ebupụta. Ọ bụ ngwakọta ma ọ bụ ihe ngwọta a eke ma ọ bụ sịntetik ndabere.

On chemical Ọdịdị adhesives nwekwara dị iche iche. Ọzọkwa, ha na-nkewa dị ka anọgidesi nke mmiri mmiri ma ọ bụ ntụ ntụ.

Site n'ụzọ nke bonding, ha na-na-esonụ ụdị: PVA, kọntaktị, na-ekpo ọkụ gbazee adhesives bụ ndị na-eme ihe na molekụla larịị.

Ịrịba Ama nkesa uru adhesives, sealants. Ha na-eji nzukọ mmiri, a dịgasị iche iche nke ngwaọrụ, igwe, ventilashion usoro, wdg Ọ bụ a na-ewu ewu nyagide sealant "oge" na-ezo aka a mmiri na-eguzogide umu. Ọ na-eji maka hụ a dịgasị iche iche nke na-ebupụta - osisi, na akpụkpọ anụ, roba, iko, egbuke, wdg (Ma e wezụga ike, nke na-zubere na-eje ozi nri).

Ọ ga-kwuru na nyagide-sealant e mere na ndabere nke Polymers. N'ọnọdụ ka ukwuu, ọ bụ polysulfide, na silicone rubbers. Isi ubi nke ngwa - ejuputa dị iche iche gaps na cracks, nakwa dị ka akara nke ụzọ na windo.

Dị ka chemical mejupụtara nke nrapado-sealant bụ acrylic, silicone na polyurethane. Acryli ya ụdị a na-eji jupụta nkwonkwo na-adịghị kwa nnukwu cracks n'etiti nkume ma ọ bụ ihe na-ebupụta.

Ọ ga-kwuru na acrylic dabeere adhesives adịghị nwere solvents, ike ga-eji mechie obere cracks na n'èzí na n'ime ogige. Ha na-ji mma adhesion ka ihe, plaster, nakwa dị ka osisi na brick, ike 15 nkeji na-etolite a film na-ejigide ha Njirimara na okpomọkụ nke -25 - +80 Celsius C. Ke adianade do, ndị dị otú ahụ a sealant elu iguzogide UV ụzarị na ìhè na-etinyere kpọmkwem site tube ma ọ bụ a pụrụ iche na egbe.

Silicone data ụdị adhesives na-eji dị ka insulators, nke-eme ka ndị window etiti, ụzọ dị iche iche metal akụkụ, reliably echebe megide penetration nke mba ọzọ odors na mmiri. Ọ bụ uru na-arịba ama na silicone nyagide sealant e ji mma adhesion na iko, osisi, seramiiki na enamelled ebupụta. Ọ na-ji a elu iguzogide okpomọkụ na dị iche iche ọnọdụ ihu igwe. Dị otú ahụ adhesives dị ọtụtụ na agba ma ọ bụ colorless (uzo). Mgbe etinyere ọ ga-eti na-arụ ọrụ n'elu ga-adịkwa ọcha, ala akọrọ na degreased, na zuru ezu solidification pụtara nanị n'ụbọchị.

Polyurethane adhesives, sealants bụ densified na nnyapade uka nke nwere ike ịnọgide na-enwe a ọma ekwedo maka a ogologo oge. Ha na-eji oru ọ bụla ihe onwunwe. Ọ kwesịkwara kwuru na adhesives dabeere na polyurethane mama abụọ ebupụta ngwa ngwa, ibu siri ike n'elu kọntaktị na mmiri, nwere ike ntekwasa na a ghọọ ma ọ bụ agba. Tupu itinye ha mkpa na-ebu a ọkọlọtọ n'elu nkwadebe (ihicha na degreasing).
