Xabagta dhalada silikoon iyo xabagta mica silikoon u adkaysata heerkulka sare.
Huo Changshun iyo Chen Rufeng oo ka socda Machadka Cilmi-baarista Kiimikada ee Chenguang, Wasaaradda Warshadaha Kiimikada, iwm. ayaa horumarinaya xabagta galaaska silikoon iyo koollada mica heerkulka sare leh ee Shiinaha.Dabayaaqadii 1970-meeyadii, cts-103 xabagta silikoon, oo sida badan loo yaqaan "resin galaas silikoon", waxaa si guul leh u soo saaray hydropolycondensation of methyltriethoxysilane iyada oo ay jirto kiciye asiidh ah.Xabagta waxaa loo isticmaalay daawaynta warqadda horumarsan, ilaalinta dahaadhka birta oogada, iyo isku xidhka xaashida miica ama budada mica ee marxaladda hore.Sannadkii 1980-kii, Sanhua, Xue Zhiqing iyo Li Yansheng, oo ah soosaarayaasha xabagta ee Shanghai, siday u kala horreeyaan, waxay isticmaaleen xabag adag oo beddelaadda aashitada ku-meel-gaadhka ah.Xajmiga silikoon ee hufan iyo xidhashada u adkaysta ee sar-1 iyo sar-2 ayaa la soo saaray iyadoo lagu daray qadar yar oo dimethyldiethoxysilane ah monomethyltriethoxysilane ugu weyn.Ma jiraan wax hadhaaga aashitada inorganic ee xabagta, sidaas darteed waxqabadka kaydinta alaabtu waa mid aad u deggan, mana jirto sibidhyo la helay sannad ka dib.Sababtoo ah soo bandhigida qadar yar oo alaabta ceeriin ah oo aan shaqaynayn, alaabada sar-2 waa mid adag, dhexdhexaad ah iyo jilicsan, oo leh codsiyo ballaadhan.Waxaa si weyn loogu isticmaali karaa galaaska, balaastigga, biraha iyo qalabka kale, gaar ahaan ilaalinta caagadaha hufan sida polycarbonate, polystyrene iyo PVC, iyo for qoyaan-caddayn iyo daahan ilaalinta dahaarka ee qaybaha elektarooniga ah, kaas oo ugu dhakhsaha badan samayn doonaa weyn. wax soo saarka miisaanka.
Laga soo bilaabo 1980 ilaa 1982, Qi hongqiu, Li Yan iyo Cui Zuoming oo ka socda Machadka Cilmi-baarista Kiimikada Chenguang, iyo 1981 ilaa 1983, Xu Zhihong iyo Xue Zhiqing oo ka socda warshadda resin Shanghai waxay isticmaaleen methyltrichlorosilane oo ah alaabta ceeriin ee ugu weyn si ay u diyaariyaan silikoon heerkul sarreeya oo u adkaysta xabagta mica.Darajooyinka alaabadu waa mr-30 iyo sar-8 siday u kala horreeyaan.Marka lagu daro iska caabbinta heerkulka sare, korantada korantada, qoyaanka-cadayga, biyaha-ceybka iyo sifooyinka kale ee alaabta organosilicon ee guud, alaabtu waxay sidoo kale leeyihiin adhesion sare iyo guryaha ololka.Waxaa inta badan loo isticmaalaa soo saarista heerkulka sare u adkeysiga boorka daruuriga ah, dahaarka tuubada elektarooniga ah, heerkulka sare u adkeysiga budo daruur guddiga hooyada taageero, guddiga mica si ay u leexiyaan dahaarka gudaha mishiinka alxanka korontada, iwm. sida dahaarka aan qiiqa lahayn iyo ka-hortagga daxalka, iyo sidoo kale waxa loo isticmaali karaa sida isku-dhafka wax-ku-samaynta ee aan guban karin ama dhoobada dhoobada ah oo ka kooban laminate fiber composite fiber galaas iyo silica.Shiinuhu wuxuu qani ku yahay kheyraadka budada mica, kaas oo loo horumarin karo taxane heerkul sare ah oo u adkaysta alaabada boodhka mica.
Jiangxi Huahao waxay ku takhasustay soo saarista dimethyldiethoxysilane
Sar-8 iyo sar-9 ee warshadda xabagta Shanghai waxay qaataan hab u gaar ah habka sifa: hydrolyzes iyo alkolysis organosilicon monomers iyo xoogga iyo polycondensate isku mar.Sar-8 iyo sar-9 ayaa la soo saaray 1983kii, wax soo saarkooduna waxa uu gaadhay ku dhawaad kun tan.Waxyaabaha ugu muhiimsan ee alaabta ceeriin waa methyltrichlorosilane, markaa haddii mr-30 ama sar-8 ama sar-9 la soo saaro, qiimaha isticmaalka methyltrichlorosilane si weyn ayaa loo horumarin karaa.
Caagagga wax ka beddelka Organosilicon
Sannadihii 1960-aadkii, warshadaha duulista ee Shiinaha waxay si degdeg ah ugu baahdeen nooc caag ah oo caag ah oo silikoon u adkaysta kaas oo u adkeysan kara hadda xooggan iyo danab sare oo loogu talagalay samaynta furayaasha yaryar.Machadka Cilmi-baarista ee Beijing ee warshadaha kiimikada ayaa si guul leh u soo saaray xabagta silikoon kaas oo si toos ah hydrolyzed laga sameeyay methyltrichlorosilane lagana sameeyay caag caaryar u adkeysi leh oo leh buuxinta asbestos, kaas oo xaliyay baahida degdegga ah ee warshadaha duulista.Qalabka waxaa loo wareejiyay warshadda resin Shanghai si loo soo saaro.Si kastaba ha ahaatee, isticmaalayaashu wali waxay u baahan yihiin walxo noocan oo kale ah, markaa waa inay caawimaad waydiistaan Machadka Cilmi-baarista Kiimikada ee Chenguang, oo u guuray Gobolka Sichuan.Si loo daboolo baahiyaha degdega ah ee isticmaalayaasha, Wu Shengquan et al.Machadka wuxuu adeegsaday dariiqa uumiga hydrolysis ka methyltriethoxysilane sida walxaha bilowga ah si loogu diyaariyo xabagta silikoon ee ku dhejinta balaastikada leh waxqabadka lagu qanco, si loo xalliyo baahiyaha degdega ah ee isticmaalayaasha.
Shayga lagu xidho xabagta silikoon
Dabayaaqadii 1960-meeyadii, iyada oo horumarinta warshadaha elektiroonigga ah ee Shiinaha, waxaa lagama maarmaan ah in la isticmaalo qalabka silikoon ee leh dahaarka korantada oo aad u fiican, iska caabin heerkul sare ah, qoyaan-cadeyn iyo gubasho la'aan si loo xirto diodes awood weyn iyo kuwo yaryar, triodes, resistors, capacitors, wareegyada isku dhafan iyo qalabka kale ee elegtarooniga ah.Shiinaha, Zhang Xinghua, he Jigang, et al.Ka mid ah Machadka kimisteriga ee Akademiyada Sayniska Shiinaha, iyo Zhang Jikai, Li Yansheng, et al.Warshada resin ee Shanghai waxay hore ugu hawlanayd horumarinta xabagta sida.Waxay soo saareen badeecooyin kala duwan si ay u buuxiyaan farqiga gudaha.
dahaarka silikoon wax laga beddelay
Silikoonka guud wuxuu inta badan ka kooban yahay polymethylsiloxane iyo polyphenylsiloxane.Waafaqsanaanta xabagta silikoon ee ay ku jiraan phenyl iyo resin organic ayaa ka fiican tan xabagta silikoon ee methyl.Iska caabbinta heerkulka iyo caabbinta biyaha ee dahaarka guud ayaa lagu wanaajin karaa iyada oo la gelinayo silikoon phenyl ah iyaga.Warshadaha daahan, siloxane-waxqabad sare leh oo ay ku jirto daahan ayaa lagu diyaarin karaa isku-dhafka ama isku-dhafka phenyl ka kooban resin silicone.Horraantii 1960-kii, warshadda rinjiga ee Tianjin iyo warshadda resin Shanghai waxay si guul leh u soo saareen dahaarka xabagta synthetic oo la beddelay.Noocyo kala duwan oo siyaalo wanaagsan ah ayaa la soo saaray, sida silikoon wax laga beddelay ee epoxy resin oo leh caabbinta kulaylka wanaagsan iyo adhesion.
