Sitimakonda kunena mawu akuti sandblasting m'moyo watsiku ndi tsiku, koma amagwiritsidwa ntchito m'mbali zonse za moyo wathu. Chonchomumadziwa kwenikweni chomwe chirisandblasting? Kuti muidziwe bwino, mawu oyamba otsatirawa angakhale othandiza kwa inu.
Kuphulika kwa Abrasive
Brief Chiyambi
Abrasive bchokhalitsa ndi ndondomeko yapamwamba kumalizapa kuyendetsamediakua liwiro lalitali kwa icho. Ndi yachangu ndizosavutanjira kuchotsazonyansa pamwambakuchokera kuchitsulo, labala,kapena pulasitiki.
Kuphulika kwa abrasive kumachitika kawirikawiri kumalo otsekedwa mongazipinda zophulika kapena makabati, kapena pa malo otseguka monga pa bwato, nyumba, ndi mlatho, etc.
Mitundu
Bchokhalitsa chili ndi mitundu yambiri yofananira malinga ndi ma media osiyanasiyana:
Kuphulika kwa mchenga
Kuphulika konyowa kwa abrasive
Vkuphulika kwa apor
Kuphulitsa mikanda
Kuphulika kwa ayezi kowuma
Blasting ili ndi njira zitatu zoperekera media:
Kuphulika kwa mpweya (pneumatic)
Mawotchi amakina (kuwomba kopanda mpweya)
Kuphulika kwa Hydro (madzi opopa)
Kuphulika kwa mchenga
Mawu Oyamba Mwachidule
Monga amtundu Kuphulika kwa abrasive, sandblasting ndi njira yochizira pamwamba yomwe nthawi zambiri imakhala ndi mpweya wopondereza, tinthu tating'onoting'ono ta abrasive, ndi nozzle yopopera tinthu ting'onoting'ono tomwe timatulutsa mpweya wothamanga kwambiri. Amatchedwa sandblasting chifukwa amaphulika ndi tinthu tating'ono ta mchenga. Mchengawo ukathiridwa pamwamba, umapanga womwe ukufunikira.
Mbiri ya sandblasting ndi nozzles
Kuphulika kwa mchenga ndi chinthu chodabwitsazomwe zimachitika muchilengedwe, osati chopangidwa ndi munthu. Chifukwa chake, ngati tikufuna kuterokudziwapamene sandblasting anaonekera, izo zikhoza analondozedwa kumbuyo kwa chiyambi chakubadwawa dziko lapansi. Fumbi, mchenga,kapena tinthukuphulitsidwandi mphepo ali ndi kuthekerakusinthapamwamba pa chinthu china pa kukhudza. Tengani chitsanzo m'moyo wathu, kukokoloka kwa mphepo.
Mu 1980, mwamuna wina dzina lake BenjaminChew Tilghmananapeza chodabwitsa ichi ataona mazenera omwe anali ndi mchenga wowulutsidwa ndi mphepo. Kuwonjezera apo, anapanga makina amene amatha kuyendetsa tinthu tating’ono ta mchenga pogwiritsa ntchito mpweya wopanikiza kupita pamwamba pa zinthu. Ndi makina oyamba opangira mchenga otchedwa straight bore nozzle.
Katswiri wa masamu wa ku Switzerland ndi wasayansi Daniel Bernoulli anapeza kuti tKuthamanga kwa mpweya kumawonjezera kuthamanga kwa abrasive, yemwe amadziwika kuti Bernoulli’s Mfundo.
Kenako m’zaka za m’ma 1700, mfundo imeneyi inawonjezeredwa ndi katswiri wa sayansi ya zakuthambo wa ku Italy Giovanni Battista Venturi. Mpaka m'ma 1950, Vkupitama nozzles adawonekera ngakhale kuti Venturi adakhalapo kale.
Masitayelo Odziwika a Mchenga wa Nozzles
Kwa zaka zambiri, mitundu yosiyanasiyanaa nozzles apangidwa malinga ndi zofunas. ZaMwachitsanzo,venturi nozzle ndiye njira yabwino kwambiri yopangira mchenga. Thekuphulika kwa chitoliro chamkatimphunoismakamaka amagwiritsidwa ntchitozomvekapamwambamkatichitoliro.Ndi bAnana nozzle imagwiritsidwa ntchito makamaka kuyeretsa malo omwe ndi opapatiza kapena ovuta kuwagwira ndi nozzle wambas.
Venturi Nozzle: Nozzles za Venturi zimakhala ndi mawonekedwe ophulika omwe amalimbikitsa kuphulika bwino. Mfundo yake ndi yakuti kuchepetsa kuthamanga kwa madzimadzi kumabweretsa kuwonjezeka kwa madzi’s liwiro.
Mphuno Yolowetsa Madzi: Iwo amakhala ndi madzimadzi kusakaniza abrasive particles ndi madzi pamwamba mankhwala. Poyerekeza ndi nozzles zina, ndi wochezeka kwa thanzi kupondereza fumbi.
Mphuno Yophulika Chitoliro chamkati: Amagwiritsidwa ntchito makamaka kuyeretsa khoma lamkati la chitoliro chomwe chimaphulika mu ndondomeko ya cone.Mitundu yosiyanasiyana ya nozzles ilipozaosiyana chitoliro diameters mkati. Nthawi zina zida zowonjezera zimafunika, monga ma seti a kolala, chotengera chapakati, ndi chonyamulira chamutu chozungulira.
Nthochi Yopindika Nozzle: iye’ ngodya yopindika imalola mwayi wophulika mchenga m'malo olimba kapena olimba. Iwondi chisankho chabwino kumadera omwe ndi opapatiza kapena ovuta kuthana nawomuyezomphuno
