I-polyethylene ene-chlorine ephezulu (HCPE) iguqulwa kakhulu kuma-adhesive ngokusebenzisa i-polarity, ukuzinza, kanye nokusebenza okunikezwa yisakhiwo sayo sama-molecule. Indlela kanye nokusetshenziswa okuqondile yilena elandelayo:
1, Umsebenzi oyinhloko oguquliwe
1. Thuthukisa ukusebenza kwe-glue
Thuthukisa ukunamathela: Uchungechunge lwama-molecule e-HCPE lwe-Bontecn Group China luqukethe inani elikhulu lama-athomu e-chlorine (okuqukethwe kwe-chlorine> 61%), okwakha isakhiwo esiqinile se-polar, okuthuthukisa kakhulu ukumanzi kanye namandla okubopha amakhemikhali kwe-glue ezintweni ezifana ne-PVC, insimbi, nerabha.
Lungiselela ukuguquguquka: Amaketanga ayo ama-molecule agcwele futhi asatshalaliswa ngokungahleliwe, agwema ukugxila ekucindezelekeni, anikeze ifilimu yokunamathela ukumelana okuhle nokuguquguquka, futhi avumelane nezimo zokubopha eziguquguqukayo.
2. Qinisa izici zokusebenza
Ukumelana nokugqwala kanye nokumelana nomlilo: Okuqukethwe kwe-chlorine ephezulu (>65) kwakha isithiyo samakhemikhali sokumelana nokugqwala okuvela ku-acid, alkali, kanye ne-oyela, futhi kufeza ukuzicisha lapho kushiswa ngendlela yokubamba ama-radical amahhala e-chlorine (inkomba ye-oxygen ephezulu ≥ 60%).
Ukumelana nokuguguleka kanye nokumelana nesimo sezulu: Isakhiwo esingabophi kabili sivimbela ukuwohloka kwe-oxidative futhi sandisa isikhathi sokuphila kwesendlalelo sokunamathela ezindaweni ezinomswakama, ezishisayo, kanye ne-ultraviolet.
| Uhlobo lwe-Adhesive | Imodeli ye-HCPE | Umphumela wokuguqulwa |
| I-glue ethize ye-PVC | I-HCPE-H (i-viscosity ephezulu) | Ukufaka esikhundleni se-vinyl chloride resin ukuze kufezwe ukubopha okunamandla kwamapayipi/amashidi e-PVC |
| Ingcina ehlanganisiwe yensimbi yerabha | I-HCPE-L/M (Ukuqina Okuphansi/Okuphakathi) | Irabha ye-chloroprene/i-nitrile eqinisiwe yokuthuthukisa ukumelana nokushisa (≥ 130 ℃) kanye nokunamathelana kwe-interfacial |
| Isendlalelo esinamathelayo sokumboza okulwa nokugqwala | I-HCPE-M (i-viscosity ephakathi nendawo) | Thuthukisa ukunamathelana phakathi kokumbozwa futhi uthuthukise ngokubambisana ukuqina kokulwa nokugqwala |
3, indlela yokuguqulwa
1. Indlela yokuthuthukisa i-Polarity
Ukwethulwa kwama-athomu e-chlorine kwandisa i-polarity yama-molecule, kukhuthaza ukwakheka kwamandla e-van der Waals kanye nezibopho ze-hydrogen phakathi kwe-glue kanye nobuso obunamathele, futhi kuthuthukisa ukumanzi.
2. Ukulungiswa kokuhambisana
Hlanganisa nama-plasticizer (njenge-paraffin e-chlorine), i-acrylic resin, njll. ukuze uthuthukise izakhiwo ze-rheological futhi unciphise ukucindezeleka kwangaphakathi.
4, Izindawo zokugcina izinto
Izimo zokugcina: Kuvaliwe futhi kugcinwe ebumnyameni (izinga lokushisa elingaphansi kwama-30 ℃) ukuvimbela ukumuncwa komswakama kanye nokonakala kokusebenza, kanye nokuphila kweshelufu kwezinyanga ezingama-24.
