Kodi kugwedezeka kwachitsulo kumayambitsa kupotoka kwa PCB? Kodi maziko a granite anathetsedwa bwanji.

Pankhani yopanga zida zamagetsi, kulondola kwa kubowola kwa matabwa osindikizidwa (PCBS) ndikofunikira kwambiri, chifukwa kumakhudza mwachindunji kuyika kwa zida zamagetsi zomwe zikubwera komanso magwiridwe antchito. Pogwiritsa ntchito maziko achitsulo chachitsulo, vuto logwedezeka nthawi zambiri limapangitsa kuti mabowo a PCB asunthike, zomwe zakhala vuto lalikulu loletsa kuwongolera kulondola kwa kubowola. Maziko a granite, omwe ali ndi mawonekedwe apadera akuthupi komanso makonzedwe ake, amapereka njira yabwino yothetsera vutoli.

Choyambitsa cha kupatuka kwa borehole chifukwa cha kugwedezeka kwachitsulo
Mafupipafupi achilengedwe azinthu zachitsulo zotayidwa ndizochepa. Panthawi yogwiritsira ntchito zipangizo zobowola, makamaka pamene chobowola chothamanga kwambiri chikakumana ndi chitsulo chachitsulo, resonance imakonda kuchitika. Kumveka uku kumapangitsa kuti maziko achitsulo apangitse kugwedezeka komwe sikunganyalanyazidwe. Ngakhale kachulukidwe kakang'ono kwambiri kakugwedezeka kadzaunjikana mosalekeza ndikukulitsidwa pobowola ndendende, zomwe pamapeto pake zimatsogolera ku kubowola komwe kumapatuka pomwe adabowola poyambira. Kuphatikiza apo, kunyowetsa kwazitsulo zachitsulo kumakhala kochepa, zomwe zimapangitsa kuti zikhale zovuta kutsitsa mphamvu yakugwedezeka mwachangu, zomwe zimapangitsa kuti kugwedezeka kwanthawi yayitali ndikuchulukitse kuchulukira kwa borehole.
Makhalidwe abwino odana ndi kugwedezeka a maziko a granite
Granite ili ndi zinthu zabwino zochepetsera thupi. Kapangidwe kake kamkati ka kristalo kakang'ono kamene kamapangidwa ndipo kamatha kuyamwa bwino ndikuwononga mphamvu zonjenjemera. Pamene zida zobowola zikugwira ntchito ndikupanga kugwedezeka, maziko a granite amatha kuchepetsa kwambiri matalikidwe a kugwedezeka mu nthawi yochepa kwambiri. Kafukufuku akuwonetsa kuti chiŵerengero chonyowa cha granite ndi kangapo kuposa chitsulo choponyedwa. Izi zikutanthauza kuti imatha kutembenuza mphamvu zambiri zogwedezeka kukhala mphamvu ya kutentha ndi mitundu ina ya mphamvu nthawi yomweyo ndikuzichotsa, potero kuchepetsa kugwedezeka kwa ntchito yobowola, kuonetsetsa kuti kubowola kumatha kubowola mokhazikika motsatira njira yomwe idakonzedweratu, ndikuchepetsa bwino zochitika za zochitika zapakhomo.
Chitsimikizo cha kukhazikika kwakukulu ndi kukhazikika
Maziko a granite amakhalanso olimba kwambiri komanso okhazikika. Kachulukidwe kake ndi kokwera kwambiri ndipo mphamvu yake yopondereza ndi yayikulu kuposa yachitsulo chonyezimira. Panthawi yobowola, imatha kupirira kupanikizika kwakukulu komwe kumagwiritsidwa ntchito ndi pobowola komanso zovuta zosiyanasiyana zamakina zomwe zimapangidwira panthawi yogwiritsira ntchito zida, ndipo sizimakonda kupunduka. Ngakhale pansi pa ntchito yopitilira nthawi yayitali kapena zotsatira zazing'ono zakunja, maziko a granite amatha kusunga kukhazikika kwa kapangidwe kake ndikupereka nsanja yolimba komanso yodalirika yothandizira zida zoboola. Thandizo lokhazikikali limatsimikizira kuti malo achibale a chigawo chilichonse cha zida zobowola amakhalabe olondola nthawi zonse, motero amatsimikizira kulondola kwakukulu kwa kubowola.
Ubwino wa kukhazikika kwamafuta amapewa kugwedezeka kwina
Kuphatikiza pa kukana kwake kugwedezeka, kukhazikika kwamafuta a granite ndikwabwino kwambiri. Panthawi yobowola, kukangana pakati pa kubowola ndi pepala lachitsulo kumapangitsa kutentha, ndipo kugwiritsa ntchito zipangizozi kungayambitsenso kutentha kwapafupi. Chitsulo chachitsulo chimakhudzidwa kwambiri ndi kusintha kwa kutentha. Kuwonjezeka kwa kutentha ndi kutsika kungayambitse mosavuta mapindikidwe owonjezera ndi kugwedezeka, zomwe zimasokoneza kulondola kwa kubowola. Coefficient ya kukula kwa matenthedwe a granite ndi yotsika kwambiri. Pamene kutentha kusinthasintha, kusintha kwake kwa dimensional kumatha kunyalanyazidwa. Izi zimapewa kugwedezeka kowonjezera komwe kumachitika chifukwa cha kutentha kwa matenthedwe, kumapanga malo okhazikika ogwirira ntchito pobowola, ndikuchepetsanso kuthekera koboola.

Pofunafuna ntchito zoboola kwambiri za PCB, maziko a granite, okhala ndi kukana kugwedezeka kwakukulu, kukhazikika kwakukulu, kukhazikika kwapamwamba komanso kukhazikika kwamphamvu kwamatenthedwe, amathetsa bwino vuto loboola lomwe limayambitsidwa ndi kugwedezeka kwachitsulo kuchokera kuzinthu zingapo. Zimapereka chithandizo chodalirika cha zida zobowola za PCB, zimathandiza makampani opanga zamagetsi kupanga mapepala apamwamba osindikizidwa, ndikulimbikitsa makampani onse kuti apange njira yolondola komanso yapamwamba.
