The non-metallic screw motherboard ndi yosakhala-yamtengo wapatali yachitsulo, yomwe nthawi zambiri imagwiritsidwa ntchito pamodzi ndi ma screw plugs kapena screw bolts, ndipo imagwiritsidwa ntchito popanga makina ndi mafakitale. Ubwino wa zinthuzo umachokera ku 19th century British metallurgy, yomwe ili ndi ubwino ndi kuipa kwa British metallurgy, ili ndi makhalidwe ofooka osagwirizana ndi dzimbiri komanso kuwononga mankhwala, ndipo mitundu ikuluikulu imaphatikizapo thupi la Okuji, thupi la Maji, ndi zina zotero.
Chigawo chapakati cha ntchitoyo chimakhazikika, ulusi wa screw umalumikizidwa mkati mwa screw thread, screw thread imalumikizidwa ndi makina, mawonekedwe a screw ndi zinayi-zopindika, mawonekedwe agulugufe. Ma screw motherboards ambiri, ma screw motherboards, ndi zina zotero, kutengera muyeso wa dziko (monga mndandanda wa GB/T), magulu okhazikika monga kukongola, ndi zina zambiri. Zimagwirizana ndi mtundu wa zitsulo, zosakhala-zomangitsa zitsulo zachitsulo, kutha kwa magetsi, kutsika kwamafuta, kusachita dzimbiri mwamphamvu ndi zina, komanso kufunikira kwa malo osinthika-masoketi ambiri. Dongosolo lake lowerengera limaphatikizapo zamagetsi, mawonekedwe azamalamulo, mawonekedwe ndi mapangidwe ena ogwirira ntchito, komanso kufunikira kokhazikika kwamakampani omwewo.
Kuhitila mumuchima wahaya nyaka, nyidimu yikwawu yinateli kutukwasha kwikala nachikuhwelelu chakola. ndi mkulu; Mtundu wa thupi, mtundu wa thupi la Oku, mtundu wa thupi la Oku, -osagwirizana ndi chitsulo, kuwonjezeka; Chitsulo chophatikizika kwambiri; Chitsulo chophatikizika, mtundu wa chitsulo cha mtundu wa chitsulo cha Japan chosakhala-chitsulo chachitsulo maginito, chamtundu wa Okushi chosakhala-chitsulo chachitsulo chosakhala-chopanda maginito, koma chozizira Chikawumitsidwa, thupi limasintha, ndipo mphamvu ya biomagnetic imapangidwa.
Kugwirizana kwachitsulo chosalumikizidwa, Zowonetsa mizere yapansi pamizere yapadera:
(1) Kuchuluka kwa magetsi kukana, pafupifupi nthawi 5 kuposa chitsulo.
(2) Large lonse kukula dongosolo nambala, wachibale zitsulo kukula 40%, moyandikana kutentha misa kutalika, waya kukulitsa dongosolo nambala nambala ndi gawo kutalika.
(3) Kutentha kochepa, pafupifupi 1/3 yachitsulo.
