Izikhonkwane zamakhemikhali amagama ajwayelekile ahlobene nezikhonkwane zensimbi, amabhawodi nezikhonkwane eziboshelwa endaweni engaphansi, ngokuvamile ukwakhiwa kwamatshe nokhonkolo, kusetshenziswa isistimu yokunamathela esekwe ngenhlaka.Izikhonkwane zamakhemikhali zibhekisela ekuhlanganiseni okusetshenziswa phakathi kwezinto zensimbi nezinto ezingaphansi.Izakhi zensimbi, kulokhu, zifaka izinduku, kuyilapho i-substrate impahla ingaba izitini noma udaka.Ama-Synthetic resin adhesives asetshenziselwa ukwakha isibopho.Zisebenza kahle kakhulu uma zisetshenziswa kuzicelo zomthwalo omkhulu.Ukubaluleka okuyinhloko kwamahange amakhemikhali kanye nokugcwaliswa ukuthi bakha izibopho eziqinile kakhulu.Lawa mabhondi empeleni anamandla uma kuqhathaniswa nezinto eziyisisekelo.Ukunamathela kwamakhemikhali kusetshenziselwa ukudala lezi zibopho futhi lokhu kusho ukuthi izinto eziyisisekelo azikutholi ukucindezeleka komthwalo.Lokhu kubenze baba inketho edume kakhulu kunamahange okunweba.La mahange aqale asetshenziswa kukhonkolo owaklanyelwe ukubamba imithwalo esindayo.
Ifaneleka kahle izinhlelo zokusebenza zomthwalo ophezulu, cishe kuzo zonke izimo isibopho esiphumela sinamandla kunesisekelo sezinto ngokwazo futhi njengoba uhlelo lusekelwe ekunamatheleni kwamakhemikhali, ukucindezeleka okungekho umthwalo kunikezwa kusisekelo sezinto njengamahange ohlobo lokunweba futhi ngakho-ke ilungele ukulungiswa okuseduze konqenqema, ukuncishiswa kwesikhungo kanye nokubambelela kweqembu futhi kusetshenziswe kukhonkolo yekhwalithi engaziwa noma amandla aphansi okucindezela.Okunye okubalulekile kwamahange amakhemikhali kanye nokugcwaliswa ukuthi afanele ukulungisa izinto eziseduze konqenqema.Kungenzeka futhi ukuyisebenzisela ukubopha usebenzisa amandla ancishisiwe okucindezela.
Izinhlobo zamahange amakhemikhali asetshenziswa ezakhiweni
Kunezinhlobo ezinhlanu zamahange amakhemikhali asetshenziswa ezakhiweni ezinemininingwane ehlukene, ngayinye yazo ihlaziywa ngezansi.
Polyester chemical ihange
Amahange amakhemikhali e-polyester awuhlelo olujwayelekile lokunamathisela umjovo emakethe okulula ukulusebenzisa nokusetshenziswa kabanzi.Izingxenye ezi-2 zigcwaliswa ngosayizi abahlukahlukene be-cartridge ejovwa kabili.Kuyi-resin esebenzayo esetshenziselwa ukukhiqizwa kwe-2-component injection mortar.Asetshenziselwa ukulungisa amadowels ensimbi, izitebhisi, ama-handrails, ama-facades wokwakha, imingcele yomsindo, amapayipi, ama-awnings, amabakaki, ukuxhunywa kwe-rebar yangemuva kokufakwa.Ingaphinde isetshenziselwe ukulayisha okuphakathi, induku enentambo kanye ne-rebar anchoring kukhonkolo owomile noma isisekelo esingaklebhukile.
Ihange lekhemikhali ye-Polyester engafakwanga
Ihange lekhemikhali le-polyester elingagcwele liyinhlaka esebenzayo esetshenziselwa ukukhiqizwa komjovo wezingxenye ezi-2, lapho zombili izinhlaka ze-polyester ezingagcwalisiwe zincibilika ku-styrene (uhlobo lwe-resin yasekuqaleni) kanye nezinhlaka ze-polyester ezingena-styrene ezinama-monomer ahlobene ne-styrene njengesixazululi esisebenzayo. zisetshenziswa.Amafomula ahlukahlukene anikezela ngezinhlobonhlobo zezinhlelo zokusebenza nezinzuzo.Emikhiqizweni yesimanje, ama-resin asezingeni eliphansi aklanyelwe ukusetshenziswa ekwenziweni kwamatshe kanye nezicelo zikakhonkolo ezingakhihliwe.Ngenkathi ekugcineni, ama-methacrylate nama-epoxies ahlanzekile angasetshenziswa ezinhlelweni ezicindezelayo, njengokhonkolo oqhekekile, i-rebar nezimo zokuzamazama komhlaba.
I-epoxy acrylate chemical anchor
I-epoxy acrylate chemical anchor iyi-resin enezingxenye ezimbili ze-styrene free epoxy acrylate ezosetshenziswa kukhonkolo nakumatshe.Idizayinelwe njengendlela yokwelapha ngokushesha, ihange eliqinile lokulungisa inhlaka yemithwalo ephezulu kakhulu kanye nokulungiswa okubalulekile ikakhulukazi ezindaweni ezibolayo noma ezimweni ezimanzi.Isebenza emithwalweni esindayo, esebenza kahle kakhulu, ukuphulukiswa ngokushesha kanye nephunga eliphansi, ngokusekelwe kubuchwepheshe be-vinylester obungena-styrene obunokusebenza kabusha okuphezulu.Inikeza ukumelana namakhemikhali okuhle kakhulu ezindaweni ezinolaka kakhulu noma ngaphansi kwezimo ezinomswakama, ngisho nasezindaweni ezingaphansi kwamanzi.Ibuye isetshenziselwe ukulungisa izisekelo zokwakha eziqinile noma izinto ezingenalutho, ezindongeni, amakholomu, ama-facade, phansi, njll.
Ihange lamakhemikhali epoxy elihlanzekile
I-Pure Epoxy Standard iyisistimu ye-anchoring yezingxenye ezimbili yezingxenye ezimbili ezingu-1:1 ukuze isetshenziswe kukhonkolo oqhekekile futhi ongaklebhukile ngaphansi kwezimo ezivamile nezizamazama komhlaba.Yakhelwe izinhlelo zokusebenza ezidingeka kakhulu zesakhiwo nokuxhumeka kwe-rebar, i-Chemical Anchor Pure Epoxy Standard iqinisekisa umthamo ophezulu kakhulu wokuthwala.Yakhelwe ikakhulukazi Imboni Yezokwakha.Zimbalwa izinhlelo zokusebenza ezihlanganisa ukusetshenzelwa kwezinti ezinentambo, imigoqo eqinisayo noma imikhono yenduku enentambo yangaphakathi ibe ukhonkolo (okuvamile, okungenazimbotshana nokukhanya) kanye nobucwebe obuqinile.Inamandla ebhondi aphezulu kakhulu ekuhlulekeni kwekhonkrithi, ngaleyo ndlela iyenze ifanelekele izimo zezulu ezibushelelezi kakhulu.Ifaneleka kahle izicelo zomthwalo ophezulu, isibopho esiba umphumela sinamandla kunesisekelo sezinto ngokwazo futhi njengoba uhlelo lusekelwe kumgomo wokunamathela, akukho ukucindezeleka komthwalo owengeziwe okunikezwa kusisekelo sezinto njengamahange ohlobo lokunweba ngakho-ke alungele eduze nokulungiswa konqenqema, isikhungo esincishisiwe kanye ne-anchoring yeqembu futhi isetshenziswe kukhonkolo yekhwalithi engaziwa noma amandla aphansi okucindezela.
Amasistimu amaHybrid
Isistimu eyingxubevange ihlanganisa izingxenye ezimbili zehange lamakhemikhali eliklanyelwe ukwelapha ngokushesha ukuze ukwazi ukulayisha indawo yokubopha ngaphambi kwesikhathi kunokuba ubungakwenza ngehange le-epoxy.Ingasetshenziswa noma yikuphi lapho idinga induku enentambo noma i-rebar ibe ukhonkolo.Kungakhathaliseki ukuthi udinga i-anchorage ekuxhumekeni kwensimbi yesakhiwo njengamapulangwe ensimbi noma amakholomu kukhonkolo, izakhiwo ezinjengama-rack, imigoqo yomsindo noma uthango, ama-resin asebenza kakhulu angajovwa emgodini ngaphambi kokufakwa kwesigxobo sensimbi noma ibhawudi.Ingxube esabelayo igcwalisa konke okungahambi kahle futhi yenza imbobo ingangeni moya ngokunamathela okungu-100%, okudala amandla engeziwe omthwalo.Iphinde iqinise ukwakheka kwezindonga zikakhonkolo kanjalo nokuzungeza i-borehole, ikwenze imelane nokuqhekeka.Okokugcina, i-chemical anchoring ivumela isifaki ukuba senze izinguquko kancane ekuqondaneni kwe-stud ngenkathi ingxube yamakhemikhali isalapha.
Isiphetho
Uma ungenalo ulwazi mayelana nekhwalithi kakhonkolo owusebenzisela ukwakha, amahange amakhemikhali ayisinqumo esihle.Kunamasistimu okulethwa ahlukene nokuhluka ongakhetha kukho uma uhlose ukusebenzisa amahange amakhemikhali.Nokho, bonke bathembele esimisweni esiyisisekelo esifanayo.Basebenzisa i-base resin, ehlanganiswe nenye into ukuze baqale inqubo yokwelapha.Kubalulekile ukuhlola izinketho ezihlukahlukene ze-resin ezitholakalayo ukuze uqonde ukubaluleka kwamahange amakhemikhali.Amahange amakhemikhali cishe anokushumeka okujulile okungenamkhawulo, ngakho-ke ungakwazi ukushumeka noma yibuphi ubude benduku embobeni ukuze ukhuphule umthamo womthwalo.
