Ingaruka yumutungo wibanze wa basalt udahungabana kubikorwa nyabyo nibikorwa byo kunoza

2025-06-20

Bisa na karuboni fibre na Ikirahure, umusaruro wa fibre ya basalt ikomeza bisaba ibikoresho fatizo. Hariho itandukaniro rikomeye mubyiza nibisabwa mubikorwa bya fibre ya basalt yo mu turere dutandukanye. Ndetse no mukarere kamwe, itandukaniro rirahari muri basalt kuva mubice bitandukanye byikirombe kimwe.

Mu bikorwa, ibibazo bitatu by'ingenzi byagaragaye:

. Ibikoresho nkibyo bikunda guhita bihita bishushanya, bisenya fibre kandi bikagabanya imbaraga zingana.

(3) Imiti ibice byubwoko butandukanye bwibikoresho fatizo bya basalt biratandukanye, bigira ingaruka kumikorere yimikorere ya fibre ya basalt ikomeza yakozwe.

Kugira ngo ikibazo cy’ibikoresho bidahungabana gikemuke, hashingiwe ku ngingo zavuzwe haruguru, ingamba zikurikira zirashobora gufatwa kugirango tunonosore:

Hitamo ibikoresho byiza bya basalt ubutare bwibanze. Ubutare bwa Basalt bugomba kuba bumwe, bukagira urwego rwo hasi rwa kristu, nta fenocriste nini, ibice bike, ikirere gike, kandi nta mwanda wo hanze nka quartz na chert. Ibigize imiti yubutare bwa basalt bigomba kuba mubipimo bifatika. Byongeye kandi, igomba kugira coefficente ikwiye ( $M._{a}$ ) mu rwego rwa $3.5 \sim 5.8$ , hamwe n'ubukonje ( $l g cyangwa$ ) ya $0.5 \sim 1.4 Nibyiza \cdot s$ . Ubukonje ( $cyangwa$ ) ya silikate ishonga nigikorwa cyubushyuhe, umuvuduko, hamwe nibigize, kandi birashobora kugaragazwa nuburinganire bwa Arrhenius: $l g cyangwa = l g cyangwa_{0} + NA_{cyangwa} / RT$ , aho $cyangwa_{0}$ ni ihoraho (pre-exponential factor) na $NA_{cyangwa}$ ni imbaraga zo gukora zo gutembera neza gushonga. Ubutare bwa Basalt bugomba kugumana ubushyuhe bwagutse mugihe cyo gushushanya, bigatuma gushonga no gushushanya byoroshye, kandi bigomba kuba birimo ntanubushyuhe bwo hejuru bwihanganira ubukonje nka olivine na corundum.
Shimangira ibikoresho fatizo homogenisation. Ibikoresho fatizo byujuje ibisabwa birajanjagurwa, bikerekanwa, kandi bigahuzwa hakoreshejwe ibikoresho kabuhariwe mbere yo koherezwa muri silo yabanjirije itanura. Kugirango hamenyekane ubwiza bwibikoresho fatizo byamabuye, ingano yingingo zigomba guhora zihamye. Ibice binini cyane birashobora gukurura gushonga, mugihe uduce duto cyane dushobora kugabanya ubwiza bwashonga.
Kuvanga ibikoresho byiza bya basalt ubutare bwibanze. Bitewe nuburinganire bugizwe nubutare bwa basalt karemano, hamwe namabuye y'agaciro atandukanye afatanya kandi akabana, hamwe namabuye y'agaciro atandukanye afite aho ashonga, niba ibikoresho fatizo ari kimwe rwose ni kimwe mubintu byingenzi bigira ingaruka kumusubizo. Kugirango ushongeshe neza ibikoresho no kunoza imikorere ya fibre yavuyemo, ibigo bimwe na bimwe bitanga umusaruro byakoresheje uburyo "bwogukora ibihimbano", baguza umusaruro wibirahure. Ibi bikubiyemo gutegura ibikoresho fatizo ukurikije ibipimo ngenderwaho, guhitamo ubuziranenge bwiza bwa basalt, no kuyihindura ukurikije indangagaciro zisanzwe ukoresheje "gutanga ibibuze" na "byera kubyera" - urugero, kuzuza calcium niba ibuze. Byongeye kandi, kubicuruzwa bifite imikorere yihariye isabwa, guhitamo doping byatoranijwe birashobora gukorwa kugirango ibipimo ngenderwaho byose byujuje ibyangombwa bisabwa, nka fibre irwanya alkali, fibre irwanya ubushyuhe bwinshi, hamwe nimbaraga nyinshi, fibre-modulus. Ibi bisaba guhitamo ibikoresho byamabuye y'agaciro cyangwa ibindi bikoresho bya basalt kugirango "doping modification" ikwiye y'ibikoresho fatizo bya basalt.
