Sika Sealants: Intangiriro y'ikirango, porogaramu y'ibicuruzwa n'uburyo butandukanye bwo gukoresha

Sika yashinzwe mu 1910, ifite icyicaro gikuru i Zurich, mu Busuwisi, ni ikigo cy’ingenzi ku isi mu buvuzi bwihariye mu bwubatsi no mu nganda. Ifite imyaka irenga 110 y’udushya, Sika ikorera mu bihugu birenga 76, itanga ibisubizo byo mu rwego rwo hejuru byo gufunga, gufatanya no kwirinda amazi bishyiraho amahame ngenderwaho mu nganda. Sika ifunga ibintu—ikubiyemo imiti yihariye mu bwubatsi no mu nganda.Sikaflex® polyurethane, Silikasilike ya Sikasil®, n'ikoranabuhanga rya polymer rivanze—rizwiho kuramba, uburimbane, kurwanya ikirere, no kutabangamira ibidukikije, bigatuma biba ngombwa cyane mu nzego z'imiturire, ubucuruzi, ubwubatsi bw'ubwubatsi, n'ingandaSika Group. Iyi nkuru irasuzuma ikoranabuhanga ry'ingenzi rya Sika rishyiraho uburyo bwo gufunga, ibicuruzwa by'ingenzi, n'ikoreshwa ryabyo mu buryo bwagutse.

Ikoranabuhanga rya Core Sealant n'Ibyiza by'Ibicuruzwa

Porogaramu ya Sika yo gufunga ishingiye ku ikoranabuhanga ritatu ry’ibanze, buri koranabuhanga rijyanye n’ibikenewe mu mikorere yihariye:

1. Sikaflex® Polyurethane Sealants

Ibyuma bifunga polymer bya Sika bivangwa na silane bihuza ibyiza bya polyurethane na silikoni: bidafite isocyanate, bifite VOC nke, bishobora gusigwa irangi, kandi birushaho kumera neza. Bitanga umusaruro mwiza ku mishinga y'ubwubatsi bw'icyatsi kibisi.

Ku mirongo yose, Sika sealants isangiye imbaraga z'ibanze:imyuka ihumanya ikirere mike(guhura na EU REACH na RoHS),gukira vuba, porogaramu yoroshye, naigihe kirekire cyo gukora—ni ingenzi mu kugabanya ikiguzi cyo kubungabunga no kunoza uburyo inyubako ziramba.

Imirongo y'ibicuruzwa by'ingenzi n'ikoreshwa ry'ingenzi

Ibyuma bifunga amazu bya Sika byagenewe gukemura ibibazo byose byo gufunga amazu, kuva ku kuvugurura amazu kugeza ku bikorwaremezo binini.

1. Ubwubatsi n'Ivugurura ry'Imiturire

• Sikasil®-A10 na Sikasil®-C: Ibifunga bya silikoni bitagira aho bibohera, birwanya ibihumyo mu bwiherero, mu gikoni no mu bwogero. Birinda amazi kwinjira no gukura kw'ibihumyo, bigatuma ibifunga bihora bisukuye kandi biramba hafi y'ubwogero, mu masinki no mu bwiherero.
• Sikasil®-F10/F11: Ibifunga bya silikoni bidahura n'ikirere bifunga amadirishya n'umuryango. Biziba umuyaga, bigabanya ibura ry'ingufu, kandi bihangana n'ikirere cyo hanze, bikongera ihumure n'imikorere myiza mu rugo.
• Sikaflex®-11FC: Ifite uburyo bwinshi bwo gufunga polyurethane ikoreshwa mu guhuza imbere, imbere mu nzu, no gusana ibintu bito. Irangi kandi yoroshye kuyisiga, ivanga neza n'imitako.

Impamvu Sika Sealants ari zo ziyoboye isoko

Ubwiganze bwa Sika bukomoka ku nkingi eshatu:udushya mu bya tekiniki, kugenzura ubuziranenge, nakurambye. Iyi sosiyete ishora imari nyinshi mu bushakashatsi n'iterambere, aho ibigo by'ibizamini ku isi bigenzura ko ibicuruzwa byujuje cyangwa birengeje ISO, ASTM, n'amategeko agenga inyubako yo mu gace Sika Group ikoreramo. Sika sealants nazo zagenewe uruziga: formulaire nyinshi zishobora kongera gukoreshwa, zifite VOC nke, kandi zigira uruhare mu gutanga ibyemezo by'inyubako za LEED na BREEAM.

Ku ba rwiyemezamirimo, abubatsi, na ba nyir'amazu, Sika itanga ibirenze ibicuruzwa gusa—itanga ubufasha burambuye: inama za tekiniki, amahugurwa yo mu kigo, n'ibisubizo byihariye ku mishinga igoye ya Sika Group. Ubu buryo buhuriweho bwatumye Sika iba umufatanyabikorwa wizewe w'inyubako zizwi ku isi yose, kuva ku nyubako ndende kugeza ku biraro kugeza ku midugudu yo guturamo.

Umwanzuro

Ibyuma bifunga Sika bigaragaza urugero rwiza mu ikoranabuhanga ryo gufunga, bivanga ubuziranenge bw'Ubusuwisi n'uburyo bwo guhuza ibintu ku isi yose. Byaba gufunga amatafari yo mu bwiherero, urwego rw'igorofa, cyangwa umuhanda munini, Sika itanga imikorere ihamye kandi irambye irinda inyubako, yongera imikorere myiza, kandi igashyigikira imikorere irambye y'inyubako. Uko inganda z'ubwubatsi zigenda zitera imbere zigana ku bikorwa remezo bito kandi birambye, ibisubizo bishya bya Sika bizakomeza kugira uruhare runini mu kurema ibidukikije byubatswe mu myaka ibarirwa muri za mirongo iri imbere.
