Ma slabs a granite, omwe ali ndi kulimba kwawo kwakukulu, kutsika kwa kutentha kwapakati, ndi kukhazikika kwapamwamba, amagwira ntchito yofunika kwambiri pakuyeza molondola ndi kupanga makina. Kuti muwonetsetse kuti nthawi yayitali imakhala yolondola komanso yokhazikika, kupanga chithandizo ndi kukonzanso kotsatira ndikofunikira. Nkhaniyi ifotokoza mfundo ndi njira zopangira chithandizo chamankhwala, komanso mfundo zazikuluzikulu za chithandizo chotsatira ndi kukonza.
1. Chithandizo cha Shaping: Mwala Wapangodya Wakulondola Kwanthawi yayitali
Pachimake pakupanga chithandizo cha granite slabs ndikuchotsa kupsinjika kwamkati ndikukhazikika kwa microstructure, ndikuyika maziko okonzekera ndikugwiritsa ntchito motsatira.
Chithandizo cha Ukalamba Wachilengedwe
Miyala ya granite imachokera ku miyala yomwe ili pansi pa nthaka. Zovuta zamkati zakhala zikuwunjikana pakapita nthawi kudzera munjira za geological. Kukalamba kwachilengedwe kumaphatikizapo kuika zinthu zokumbidwa m’miyendo ku nyengo, kuchititsa mphepo, dzuwa, ndi mvula kwa zaka zambiri. Panthawi imeneyi, kusinthasintha kwa kutentha, kusinthasintha kwa chinyezi, ndi mphamvu ya mphepo zimamasula pang'onopang'ono kupsinjika kwa mkati mwa thanthwe. Mwachitsanzo, thanthweli limakula m’nyengo ya chilimwe kutentha kwambiri komanso kumachita zinthu m’nyengo yozizira kwambiri. Kupindika kobwerezabwereza kumeneku kumabalalitsa pang'onopang'ono ndikuchotsa nkhawa. Pambuyo pa ukalamba wachilengedwe, mawonekedwe amkati a granite amakhala ofanana kwambiri, zomwe zimapangitsa kuti zisawonongeke chifukwa cha kupsinjika maganizo panthawi yokonza makina, motero kuonetsetsa kuti slab ikulondola.
Ukalamba Wopanga
Kwa ma slabs a granite omwe amafunikira kulondola kwambiri, ukalamba wachilengedwe wokha nthawi zambiri umalephera kukwaniritsa zomwe mukufuna. Kukalamba kochita kupanga ndikofunikira. Silabu nthawi zambiri imayikidwa mu ng'anjo yotentha yokhazikika, yotenthedwa pang'onopang'ono mpaka kutentha kwina, ndikusungidwa pamenepo kwa nthawi yayitali. Kutentha kwakukulu kumawonjezera ntchito ya mineral particles mkati mwa thanthwe, kutulutsanso kupsinjika maganizo. Pambuyo pake, kutentha kumatsitsidwa pang'onopang'ono, zomwe zimapangitsa kuti miyalayo ikhale yolimba panthawi yozizira komanso kuteteza kupsinjika kwatsopano kuti zisapangidwe ndi kuzizira kofulumira. Kukalamba kochita kupanga kumapangitsa kuti pakhale kuwongolera bwino kwamankhwala, kufupikitsa nthawi yokonzekera, ndikuwonjezera kukhazikika kwa slab.
Zovuta komanso zomaliza
Pambuyo pa ukalamba, slab ya granite imakhala yovuta komanso yomaliza. Panthawi yovuta, makina akuluakulu ophera kapena chopukusira amagwiritsidwa ntchito kuchotsa malo ochulukirapo, poyambira kubweretsa slab mkati mwazomwe zafotokozedwa. Panthawiyi, kudula kwa voliyumu ndi liwiro la kudula kuyenera kuyang'aniridwa mosamalitsa kuti musagawitsenso kupsinjika mkati mwa slab chifukwa cha kudula kwambiri kapena mphamvu zodulira. Semi-finishing, yotengera kukhwinyata, kumapangitsanso kusalala kwapamwamba komanso kulondola kwapang'onopang'ono kwa slab. Kupyolera mukupera kobwerezabwereza, mosamala, pamwamba pa slab imasinthidwa pang'onopang'ono, ndikuchotsanso ma micro-stress omwe amapangidwa panthawi ya makina, kukonzekera kuti amalize.
II. Pambuyo Kukonza ndi Kukonza: Kusunga Kulondola Kwambiri kwa Slab
Ma slabs a granite amatha kutengera zinthu zosiyanasiyana pakagwiritsidwe ntchito, kuphatikiza zinthu zachilengedwe ndi kagwiritsidwe ntchito, motero amafunikira kukonzedwa koyenera ndi kukonzanso.
Kuyeretsa ndi Kusamalira Tsiku ndi Tsiku
Pogwiritsidwa ntchito tsiku ndi tsiku, ma slabs a granite amadziunjikira mosavuta zonyansa monga fumbi ndi mafuta pamalo awo. Gwiritsani ntchito nsalu yoyera, yofewa kapena fumbi la nthenga kuti muchotse fumbi pang'onopang'ono. Pewani kugwiritsa ntchito nsalu zolimba kapena maburashi olimba, chifukwa amatha kukanda pamwamba. Kwa madontho amakani monga mafuta, gwiritsani ntchito zotsukira zopanda ndale. Pang'onopang'ono pukutani malo okhudzidwawo ndi nsalu yofewa yonyowa ndi madzi oyera. Muzimutsuka bwino ndi madzi aukhondo ndi kupukuta zouma ndi nsalu youma kuteteza chinyezi chotsalira ndi madontho a madzi. Kuyeretsa nthawi zonse kumasunga ukhondo wa pamwamba pa slab ndikuletsa zonyansa kusokoneza kulondola kwa miyeso.
Kuwongolera Zachilengedwe
Ma slabs a granite amakhudzidwa ndi kutentha kozungulira komanso chinyezi. Ayenera kusungidwa m'nyumba m'malo okhazikika, opanda chinyezi, kutali ndi dzuwa komanso kutentha kwambiri. Kusinthasintha kwa kutentha kwachangu kungapangitse kuti slab ikule ndi kutsika, kusokoneza kulondola kwake. Chinyezi chochuluka chimapangitsa kuti chinyontho chilowe pamwamba, zomwe zimapangitsa kutupa komweko. Komanso, sungani slab kutali ndi magwero a kugwedezeka ndi mpweya wowononga, chifukwa kugwedezeka kungakhudze kukhazikika kwa slab, pamene mpweya wowononga ukhoza kuwononga pamwamba ndikufupikitsa moyo wake wautumiki.
Kukonza Nthawi Zonse ndi Kukonza
Ma slabs a granite amatha kutaya kulondola pang'onopang'ono pakapita nthawi. Chifukwa chake, kuwongolera nthawi zonse ndikofunikira. Gwiritsani ntchito zida zoyezera zolondola kuti muwone kusalala kwa slab, perpendicularity, ndi magawo ena, ndikukonza koyenera kutengera zotsatira. Zovala zazing'ono kapena zokopa zimatha kukonzedwa ndi kugaya pamanja. Gwiritsani ntchito phala la abrasive-grained ndi mwala wamafuta, kugwiritsa ntchito njira yoyenera yopera ndi kukakamiza kuti pang'onopang'ono mubwezeretse kulondola kwa pamwamba pa slab. Kuvala kwambiri kumafuna kukonzedwanso ndi wopanga waluso.
