Yintoni umahluko phakathi kwe-polyethylene ene-chlorine eninzi kunye nerabha ene-chlorine?

I-polyethylene ene-chlorine ephezulu (HCPE) kunye nerabha ene-chlorine (CR) eziveliswa yiBontecn Group China zii-polymers ezimbini ezisetyenziswa kakhulu kwimida yeengubo ezichasene nokugqwala kunye nezincamathelisi, kodwa zinomahluko omkhulu kwisakhiwo seekhemikhali, iimpawu zokusebenza, kunye neemeko ezifanelekileyo.
1. Ulwakhiwo lweekhemikhali kunye nobuhlobo nokusingqongileyo
I-HCPE: Ilungiselelwe ngokuguqulwa kwe-chlorination ye-polyethylene, kunye nokusasazwa okungacwangciswanga kwee-athomu ze-chlorine kunye nomxholo we-chlorine oqhele ukuba yi-≥ 65%. Yenziwe ngendlela yokumiswa kwamanzi, ayinayo i-solvent ungcoliseko kwaye ihlangabezana neemfuno zokhuseleko lokusingqongileyo.
CR: Yenziwa ngokufaka i-chlorine kwirabha yendalo okanye irabha yokwenziwa, enomxholo we-chlorine omalunga nama-60-65%. Ukuveliswa kwesinyibilikisi sendabuko kunokubangela izinto ezinobungozi eziseleyo kunye nokukhuselwa okungalunganga kokusingqongileyo.
2. Uthelekiso lwentsebenzo
Ukumelana nemozulu: I-HCPE inokumelana okuphezulu kwe-ozone kunye ne-ultraviolet, nto leyo eyenza ukuba ifaneleke kwiindawo ezihlala ixesha elide ngaphandle ezifana neebhulorho kunye neenqanawa; I-CR isengozini yokuwohloka kumaqondo obushushu aphezulu kwaye inokumelana nemozulu okubuthathaka.
Ukumelana neekhemikhali: Zombini ziyamelana ne-asidi kunye ne-alkali, kodwa i-HCPE iyakwazi ukunyamezela ii-oxidants ezinamandla (ezifana ne-sulfuric acid egxininisiweyo), ngaphandle kokuqhuma okanye ukuchitheka emva kweentsuku ezingama-30 zovavanyo.
3. Umahluko kwiinkalo zesicelo
I-HCPE:
Ugqubuthelo olunzima lokulwa nokugqwala (izixhobo zeekhemikhali, imibhobho ye-oyile)
Izinto ezithintela ilangatye (iinwele ezingatshiyo, iishelufu zekhebula)
Iglue ephezulu (yokubopha ngePVC kunye nesinyithi)
CR:
Iingubo zemveli zokulwa nokugqwala (zeenqanawa kunye neenkonkxa)
I-inki kunye nentsimi yokuprinta
4. Imarike kunye neendleko
I-HCPE: Ngenxa yeendleko eziphezulu zeenkqubo ezinobuhlobo nokusingqongileyo kodwa ukusebenza ngcono ngokubanzi, ithatha indawo ye-CR kancinci kancinci.
CR: Ixabiso liphantsi, kodwa ngenxa yemigaqo yokusingqongileyo, umda wokusetyenziswa ulinganiselwe.
5. Ukusetyenziswa okuxhasayo
Zombini ziyahambelana nezinye iiresini ezifana ne-epoxy resin kunye ne-acrylic acid, kodwa i-HCPE ifanelekile ngakumbi kwiinkqubo zokugquma ezidityanisiweyo ezifuna ukunamathela okuphezulu okanye ukumelana nemozulu.
