Indawo yesimanje yokwakha ichazwa ngokusobala kanye nobuqotho besakhiwo sesakhiwo. Enhliziyweni yalesi "Sikhathi Esisekelwe ku-Silicon" sokwakha kukhonaisivalo sesakhiwo se-silicone, izinto eziye zavela ekuzivumelaniseni kwezinto eziphilayo, ezisekelwe kukhabhoni zaya ezinhlelweni ezingaphili ezisebenza kahle kakhulu. Njengephayona embonini kusukela ngo-1984,Izivalo zeSiwayubone lokhu kuguquka kwesimo, ekhuthaza ubumsulwa bamakhemikhali ngokumelene nenkinga yanamuhla yokungcoliswa kwamafutha amaminerali (amafutha amhlophe).
Ipharadayimu Yezobuchwepheshe: Kungani I-Silicon Ibusa Izicabha Zanamuhla
Ukuguquka kusuka ezinhlelweni zezinto eziphilayo "ezisekelwe kukhabhoni" kuya ezinhlakeni zezimboni "ezisekelwe ku-silicon" kuyiqiniso elibonakalayo kubunjiniyela bokubuka ngaphambili. Ngenkathi ama-polymer e-organic ethembele ezibophweni ze-carbon-carbon (CC), ukugqwala kwesakhiwo okuphezulu kusebenzisa ukuzinza okuphezulu kwesibopho se-silicon-oxygen (Si-O).
Inzuzo Yamakhemikhali Yezibopho ze-Si-O
Ukuqina kwe-aisivalo sesakhiwo se-siliconekuwumphumela oqondile wokwakheka kwayo kwama-molecule. Amandla ebhondi le-$Si-O$ aphezulu kakhulu kunalawo ezinhlobo ezisuselwe ku-carbon, okwenza ukuthi avikeleke ngokuphelele ekuwohlokeni kwe-UV.
| Isibopho Samakhemikhali | Amandla e-Bond (kJ/mol) | Ukumelana ne-UV |
| I-Si-O | 460.5 | Kuhle kakhulu |
| I-CO | 358.0 | Okumaphakathi |
| I-Si-C | 318.2 | Okumaphakathi |
| I-CC | 304.0 | Phansi |
Lokhu kuqina kwesakhiwo kuvumela imikhiqizo yeSiway ukuthi ilondoloze ukunwebeka emazingeni okushisa aphezulu, kusukela ku--50 ℃ kuya ku-+150 ℃.
Isigaba I: Isikhathi Esisekelwe Kukhabhoni kanye Nokuyekethisa Kwezakhiwo (1980s)
Umlando wemboni yodonga lwamakhethini eShayina waqala ngo-1984 ngeBeijing Great Wall Hotel. Phakathi nalesi sikhathi, ukuntuleka kwezinamathiselo zesakhiwo ezizinikele kwaphoqa abaklami ukuba basebenzise izithiyo zemvelo ezifana nama-polysulfide noma ama-acrylic.
-
*Izivalo ze-Polysulfide: Ngokusekelwe emigogodleni ye-carbon-sulfur (CS), lezi zinto zahlushwa ukuqina nokulahlekelwa ukunwebeka lapho zivezwa emisebeni ye-UV.
-
*Imikhawulo YokuklamaNgenxa yokuthi izivalo ezisekelwe ku-carbon azikwazanga ukuthwala imithwalo yesakhiwo yesikhathi eside, izakhiwo zazinqunyelwe ezinhlelweni "zohlaka oluveziwe" (ezinamathelayo), lapho amapuleti e-aluminium ayebopha khona ingilazi ngomshini.
Isigaba II: I-Silicon Revolution kanye Nokuvuka kweSiway (1990-2000)
Maphakathi nawo-1990 kwaphawula "iNkathi Yegolide Ye-Silicon Ehlanzekile." Ukwethulwa kwe-izivalo zesakhiwo se-silicone ezingathathi hlangothikuvunyelwe ukuzalwa kwezindonga zekhethini "ezifihliwe", lapho i-sealant ngokwayo ithwala isisindo sengilazi kanye nemithwalo yomoya enamandla.
Yasungulwa ngo-1984,Izivalo zeSiway(Shanghai Siway Building Materials Co., Ltd.) yavela njengomkhiqizi ohamba phambili we-3, oqhuba ukusungula izinto ezintsha kulesi sikhala. Imigqa yethu yokukhiqiza ezenzakalelayo yesimanje iqinisekisa ukuthi akukho miphumela emibi yezinhlelo zokusebenza ezibalulekile zesakhiwo.
Izixazululo Ezivelele zeSiway Zokugqwala Kwesakhiwo
-
**I-Siway SV999: I-silicone sealant yesakhiwo se-single-component esezingeni eliphezulu eyenzelwe ukuhlanganiswa kodonga lwe-aluminium kanye ne-glass curtain. Inikeza ukunamathela okungenasisekelo kanye nekhono lokunyakaza elingu-25%.
-
**I-Siway SV9900: I-glue yesakhiwo enezingxenye ezimbili, ephola ngokushesha efanelekile ekusetshenzisweni kwamaphaneli ahlanganisiwe kanye nokwakhiwa kwezitezi eziphakeme, ehlangabezana nezidingo eziqinile ze-ASTM C1184.
- **I-Siway SV8890：I-silicone structural glazing sealant enezingxenye ezimbili ayilapheki kahle, ine-modulus ephezulu, yenzelwe ngqo ukuhlanganisa udonga lwekhethini le-structural glazing, udonga lwekhethini le-aluminium, uphawu lwesakhiwo lobunjiniyela bensimbi kanye nengilazi yokuvikela esebenza kahle kakhulu.
Isigaba Sesithathu: Ingozi Yokungcoliswa Kwamafutha Amhlophe
Njengoba umncintiswano wawukhula ngawo-2010, abanye abakhiqizi baqala ukuxuba i-silicone ngezithako ezishibhile ezisekelwe ku-petroleum ezaziwa ngokuthi "amafutha amhlophe" (amafutha amaminerali). Lokhu kumelela "ukuhlehla okusekelwe ku-carbon" okuyingozi embonini ephethwe yi-silicon.
Kungani Amafutha Amhlophe Ehluleka Ekusetshenzisweni Kwesakhiwo
Uwoyela wamaminerali (C_n H_{2n+2}) awuhambisani ngamakhemikhali nomgogodla we-$Si-O-Si$ wama-polymer e-silicone. Lokhu kungahambisani kuholela ku:
-
1. Ukufuduka Nokungcolisa: Uwoyela uyaphuma, okubangela ukuthi uwoyela "wothingo" ushelele engilazini bese kuba nombala wetshe lemvelo.
-
2. Ukuncipha Okukhulu: Njengoba uwoyela uphela, i-sealant incipha ngaphezu kuka-15%, okuholela ekuhlulekeni kwamalunga.
-
3. Ukwehluleka Kokunamathela: Ama-sealant axubile aba lukhuni futhi aqhekeke phakathi nezinyanga eziyi-6 kuya kwezingama-24, okubeka engcupheni enkulu yokuthi amaphaneli engilazi asuke ebusweni.
Ukuqinisekiswa Kwekhwalithi: Izinga le-Siway
Ukuze kuvikelwe isikhathi eside sokwakha, iSiway ilandela ngokuqinile amazinga okusebenza aphesheya kwezilwandle afanaI-ASTM C1184futhiI-GB 16776Sincoma ukuthiInqubo ye-IETukuze kulawulwe ikhwalithi endaweni:
-
*I - Ukuhlolwa: Qinisekisa ama-Technical Data Sheets (TDS) bese uqinisekisa ukuthi umkhiqizo uqukethe i-silicone polymer engu-100%.
-
*E - Ukuhlolwa: Yenza ukuhlolwa kwezinzwa kumasampula aphilisiwe ukuqinisekisa ukuthi ahlala ecwebezela futhi awabi “yimpuphu” ngokuhamba kwesikhathi.
-
*T - Ukuhlolwa: Kwezinhlelo ezinezingxenye ezimbili ezifanaI-SV9900, sebenzisa i-"Butterfly Test" ukuqinisekisa ingxube efanayo yesisekelo kanye ne-catalyst.
Izicabha Ezisimeme Ngokuhlanzeka Kwamakhemikhali
Ukuvela kodonga lwekhethini kuwuhambo oluya ekugqameni kwezinto ezibonakalayo. Ngokukhetha izinto zokuvala izakhiwo ze-silicone ezihlanzekile, abakhi bezakhiwo nonjiniyela baqinisekisa ukuthi izakhiwo zabo zihlala ziqinile iminyaka engama-25 kuya kwengama-50.
KwaSiway Sealants, sikholelwa ukuthi "Isikhathi Esisekelwe kuSilicon" kufanele sichazwe ngokuphepha kanye nokusimama. Ukuzibophezela kwethu "kwe-Green Sealant" kuqinisekisa ukuthi yonke imikhiqizo ayinawo amafutha amhlophe angcolisiwe, ivikela izinkanyezi zekusasa ngobuqotho bamakhemikhali banamuhla.
