Sungani nthawi ndikuwononga ndalama zowononga pofufuza zambiri kapena kusunga zinthu.Mabotolo athu a zitsanzo zamagalasi a silane adathandizidwa ndi njira ya silane ya vapor deposition.Thandizo la pamwamba monga silanization ndi sililicification ndizofunikira kuti zinthu zina kapena zowonjezera zomwe zimasungidwa muzitsulo zagalasi zikhale zodalirika.Kusintha kwapamwamba kumatha kuchepetsa malo omwe akugwira ntchito pa galasi la borosilicate.
The ndondomeko padziko mankhwala zitsulo kapena sanali zitsulo zipangizo ndi amadzimadzi organosilane monga chigawo chachikulu.Silanization ili ndi zotsatirazi zabwino kuposa ochiritsira phosphating: palibe zovulaza heavy metal ayoni, palibe phosphorous, ndipo palibe chifukwa chotenthetsera.Njira yochizira silane simatulutsa dothi, nthawi ya chithandizo ndi yochepa, ndipo kuwongolera kumakhala kosavuta.Njira zoyendetsera ndizochepa, kusintha kwa tebulo kumatha kusiyidwa, ndipo tanki yamadzimadzi ingagwiritsidwenso ntchito.Mogwira mtima kuwongolera kumamatira kwa utoto ku gawo lapansi.Collinear processing wa chitsulo pepala, kanasonkhezereka pepala, pepala zotayidwa ndi magawo ena.
(1) Mankhwala a silane alibe zitsulo zolemera monga zinki ndi faifi tambala ndi zinthu zina zoipa.Nickel yatsimikiziridwa kukhala yovulaza thupi la munthu.Bungwe Loona za Umoyo Padziko Lonse (WHO) likunena kuti nickel iyenera kutayidwa mpaka zero pambuyo pa 2016, ikufuna kuti faifiyo asakhale m'madzi onyansa a phosphating, phosphating vapor ndi phosphating fumbi logaya.
(2) Chithandizo cha silane chimangotulutsa silane yochepa kwambiri, ndipo mtengo wa mankhwala a slag ndi wotsika kwambiri.
Phosphating slag ndi mnzake wosapeŵeka wa chikhalidwe phosphating reaction.Mwachitsanzo, chingwe chopangira magalimoto chogwiritsa ntchito mbale zoziziritsa kuzizira chidzatulutsa pafupifupi 600g ya phosphating slag yokhala ndi 50% chinyezi pagalimoto imodzi (yoyesedwa ndi 100m2), ndipo mzere wopanga magalimoto 100,000 udzatulutsa 60t ya phosphating slag pachaka.
(3) Palibe cholimbikitsa cha nitrite chomwe chikufunika, motero kupewa kuvulaza kwa nitrite ndi kuwonongeka kwake kwa thupi la munthu.
(4) Zomwe zimagwiritsidwa ntchito ndizochepa, 5% ~ 10% yokha ya phosphating.
(5) Palibe njira monga kusintha tebulo ndi passivation mu silane mankhwala.Masitepe ocheperako komanso nthawi yayifupi yopangira ndiwothandiza kupititsa patsogolo mphamvu zopanga fakitale, kufupikitsa mzere watsopano wopangira, ndikusunga ndalama zamagetsi ndi malo apansi.
(6) Kutentha kwachipinda ndi kotheka, kupulumutsa mphamvu.Silane thanki yankho siliyenera kutenthedwa, ndipo phosphating yachikhalidwe nthawi zambiri imafuna 35 ~ 55 ℃.
(7) Palibe kutsutsana ndi njira yomwe ilipo, ndipo palibe kusintha kwa zida komwe kungasinthidwe mwachindunji ndi phosphating;Zimagwirizana ndi njira yoyambira yoyambira ndipo imatha kufananizidwa ndi mitundu yonse ya utoto ndi utoto wogwiritsidwa ntchito.
Galasi ya Borosilicate ndi chinthu chodziwika bwino cha Mbale za HPLC chifukwa imakhala ndi mankhwala abwino kwambiri komanso kukana kutentha.Galasi yamtunduwu ndi yoyenera kwa ntchito za HPLC chifukwa imatha kupirira kutentha kwambiri komanso zosungunulira zamphamvu zomwe zimagwiritsidwa ntchito nthawi zambiri ku HPLC.
Posankha Mbale za HPLC, ndikofunikira kuganizira mtundu wa zitsanzo zomwe zikuwunikidwa komanso momwe kuwunikirako kudzachitikire.Amber borosilicate glass HPLC Mbale zokhala ndi 9mm kutsegula ndi chisankho chodziwika kwa ntchito zambiri za labotale chifukwa cha mawonekedwe awo abwino kwambiri komanso kuyanjana ndi zitsanzo ndi mikhalidwe yambiri.
Kuphatikiza pa vial yokha, septa imafunikanso pakuwunika kwa HPLC.Septa ndi kachidutswa kakang'ono, kozungulira kamene kamalowa mu vial ndipo imakhala ngati chisindikizo.Zimalola kukhazikitsidwa kwa chitsanzo mu vial komanso kumapereka chotchinga pakati pa chitsanzo ndi syringe ya HPLC, kuteteza kuipitsidwa.Posankha septa ya HPLC Mbale, ndikofunika kuganizira mtundu wa zitsanzo zomwe zikuwunikidwa ndi mikhalidwe yomwe kusanthula kudzachitidwa.
