Wige ibijyanye na kashe muminota

Ikidodo bivuga ikintu gifunga gihindura imiterere yubuso bwa kashe, ntabwo byoroshye gutemba, kandi bifite aho bihurira.

Nibifatika bikoreshwa mukuzuza icyuho cyo gushiraho. Ifite imirimo yo kurwanya kumeneka, kutirinda amazi, kurwanya vibrasiya, kubika amajwi no kubika ubushyuhe. Mubisanzwe, ibikoresho byumye cyangwa bitumye byumye nka asfalt, resin naturel cyangwa resinike ya sintetike, reberi karemano cyangwa reberi ya sintetike ikoreshwa nkibikoresho fatizo, kandi huzuzwa inert nka talc, ibumba, umukara wa karubone, dioxyde ya titanium na asibesitosi. Amashanyarazi, amashanyarazi, imiti ikiza, yihuta, nibindi. Birashobora kugabanywamo ibyiciro bitatu: kashe ya elastike, gasike yo gufunga amazi hamwe na kashe. Ikoreshwa cyane mugushiraho ubwubatsi, ubwikorezi, ibikoresho bya elegitoronike nibice.

Hariho ubwoko bwinshi bwa kashe: Kashe ya Silicone, kashe ya polyurethane, kashe ya polysulfide, kashe ya acrylic, kashe ya anaerobic, kashe ya epoxy, kashe ya butyl, kashe ya neoprene, kashe ya PVC, hamwe na asifalt.

Ibintu nyamukuru biranga kashe

(1) Kugaragara: Kugaragara kwa kashe bigenwa ahanini no gutatanya uwuzuza muri base. Uzuza ni ifu ikomeye. Nyuma yo gutatanwa nudukate, urusyo hamwe nimashini yumubumbe, birashobora gukwirakwira muburyo bwa reberi kugirango bibe paste nziza. Umubare muto wamande cyangwa umucanga biremewe kandi nibisanzwe. Niba uwuzuza adatatanye neza, ibice byinshi bito cyane bizagaragara. Usibye gutatanya ibyuzuye, ibindi bintu bizanagira ingaruka kumiterere yibicuruzwa, nko kuvanga umwanda wanduye, gukonjesha, nibindi. Izi manza zifatwa nkizikomeye mubigaragara.

(2) Gukomera

(3) Imbaraga zikomeye

(4) Kurambura

(5) Tensile modulus nubushobozi bwo kwimura

(6) Gufatanya na substrate

. Ububiko bunini cyane buzaba bufite ubushishozi buke, kandi bizakoreshwa cyane kole iyo ikoreshejwe. Ariko, niba kole ikozwe neza cyane urebye gusa birenze urugero, bizagira ingaruka kuri thixotropy ya kashe. Extrudability irashobora gupimwa nuburyo bwerekanwe murwego rwigihugu.

(8) Thixotropy: Iki nikindi kintu cyimikorere yubwubatsi bwa kashe. Thixotropy ni ikinyuranyo cyamazi, bivuze ko kashe ishobora guhindura imiterere yayo munsi yumuvuduko runaka, kandi irashobora kugumana imiterere yayo mugihe nta mbaraga zituruka hanze. imiterere idatemba. Igenwa rya sag ryerekanwe nuburinganire bwigihugu ni urubanza rwa thixotropy ya kashe.
