Umehluko phakathi kwe-ejenti yokuxhumanisa kanye ne-ejenti yokuxhumanisa:
Ama-Cross-linking agents ngokuvamile abhekisela ekilasini lamakhemikhali ahlanganyela ekusabeleni kwe-cross-linking kwama-resin ukuxhuma amaqembu asebenzayo asebenzayo ku-resin ukwakha isakhiwo senethiwekhi. I-cross-linking agent ingathuthukisa kakhulu i-viscosity kanye nokuqina koketshezi olusebenzayo. Ngesikhathi esifanayo, kufanele futhi ibe nezakhiwo ezithile zokushisa kanye nokumelana nosawoti ngokwezimpawu ze-geological ze-reservoir. Ngaphezu kwalokho, ezinye izithasiselo zizongezwa ukuthuthukisa ukusebenza okuphelele koketshezi olusebenzayo.
Ama-coupling agent ngokuvamile abhekisela kumakhemikhali amancane ama-molecule aqukethe amaqembu amathathu noma ngaphezulu e-hydrolyzable carbon functional. Ukusebenzisa inani elincane kungathuthukisa ukunamathela okwaziwayo kwezinto eziphilayo nezingaphili, ukusabela kwamaqembu e-hydrolyzable hydrolyzable kanye ne-carbon. Leli qembu lingabekwa phezu kwanoma yiziphi izinto eziphilayo, okungukuthi, lingakha ibhuloho phakathi kwe-resin kanye ne-interface, landise ukunamathela kwezingubo kanye nezinamathiselo, futhi lisebenzise inani elincane.
Umehluko phakathi kwalokhu okubili awumkhulu kakhulu, futhi i-coupling agent iyisigaba sezinto ezinamaqembu amabili asebenzayo anezakhiwo ezahlukene. Amanye amaqembu asebenzayo kuma-molecule awo angasabela ngamanzi afakwe noma amaqembu e-hydroxyl ebusweni bezinto ezingaphili, kanti amanye amaqembu asebenzayo angasabela nama-molecule e-organic ukuze akhe izibopho noma ama-coupling. Kunomehluko omncane phakathi kwama-cross-linking agents nama-bridging agents, womabili angenza ama-linear molecules axhumane abe yisakhiwo senethiwekhi.
Ama-Cross-linking agents asetshenziswa kakhulu ku-izinto ze-polymer, ngoba isakhiwo sama-molecule sezinto ze-polymer sifana nomugqa omude. Ngaphandle kokuxhumanisa, amandla aphansi, kulula ukuwaphula, futhi akukho ukunwebeka. Umsebenzi we-ejenti yokuxhumanisa ungowomugqa. Izibopho zamakhemikhali zenziwa phakathi kwama-molecule, ukuze ama-molecule aqondile axhumene ukuze akhe isakhiwo senethiwekhi, okuthuthukisa amandla nokuqina kwerabha. I-ejenti yokuxhumanisa esetshenziswa erabha ngokuyinhloko i-sulfur, bese kufakwa i-accelerator.
Umehluko phakathi kwe-ejenti yokuhlanganisa kanye ne-compatibilizer:
Ngomqondo othile, zombili ziyi-surfactants ezinokusetshenziswa okuhlukile.
1. I-ejenti yokuxhumanisa isetshenziswa kakhulu phakathi kwe-inorganic kanye ne-organic, umsebenzi oyinhloko ukuthuthukisa ukuhambisana phakathi kwe-filler kanye ne-resin molecular chain, ukusabalala okuphezulu kwe-filler ku-resin, njenge-silane kanye ne-titanate coupling agent;
2. I-compatibilizer isetshenziselwa ukuthuthukisa ukuhambisana phakathi kwama-polymer ahlanganisiwe, okungukuthi, ukuhambisana phakathi kwama-resin amabili ahlukene ku-polymer alloy kuvame ukuba yi-polyolefin grafted maleic anhydride ekhiqizwa yi-reactive extrusion. I-GMA kanye nezinye izihlanganisi ezisabelayo, kanye nama-polymer e-polar okwenziwa.
Isikhathi esisebenzayo se-ejenti yokuhlanganisa:
Indawo lapho kusetshenziswa khona i-coupling agent efana nomswakama, isikhathi sokugcina, ukwakheka kwe-inki kanye ne-coating kanye nenani le-pH, njll. Ama-titanate nama-silane amaningi anciphile ngokwe-alkaline, futhi abola abe yi-alcohols ngenxa ye-hydrophilicity. Umphumela wawo mubi ngezikhathi zemvula nezimvula eningizimu, futhi kuthatha isikhathi eside ukoma enyakatho. Kubalulekile futhi ukuhlola ukuthi i-spray interface ayina-acid noma ayina-acid. Okuvamile Akukho lutho olungaphezu kwezintathu zochungechunge lwe-KH (silane), i-A (titanate) kanye ne-N (azo), ezisabela emanzini, utshwala, i-ether, i-ammonia, i-amine kanye ne-acid futhi zilahlekelwa ikhono lokuhlanganisa ngemva kokusabela, Ukuze kugcinwe isikhathi eside, kufanele kuqashelwe ukugwema umoya-mpilo nokuhlola njalo.
Okuqukethwe
Njengoba eseneminyaka ecishe ibe ngu-20 embonini yemishini yokukhipha izinto ezihlakaniphile, ubelokhu ephethe izindima ezibalulekile eJwell Machinery, okuhlanganisa noMphathi Jikelele kanye noSihlalo Ojikelezayo. Kusukela ngo-2024, uphathe izinkampani eziningi ezingaphansi kwakhe, eqhuba ukwanda kwebhizinisi kanye nokuthuthukiswa kwezimboni, ngenkathi ehola ukusungula izinto ezintsha ekukhiqizeni izinto ezihlakaniphile kanye nokukhula komhlaba wonke.
