iibka soo saaraha tuubooyinka biyaha polyetylen
Inner epoxy outer polyetylen tuubooyinka birta anticorrosive waa nooc cusub oo birta ka samaysan tuubo caag ah. Waxay ka kooban tahay substrate tuubooyin bir ah, dahaarka gudaha ee resin epoxy iyo daahan dibadda polyetylen. Waxay leedahay sifooyin farsamo oo aad u fiican, caabbinta daxalka iyo iska caabinta gabowga. Waxaa si weyn loogu isticmaalaa ilaalinta biyaha, awoodda korontada, warshadaha kiimikada, batroolka iyo warshado kale oo badan.
Dhuumaha birta birta ah ee ka hortagta polyetylen ee gudaha epoxide waxay u qaybsantaa: isku-dhafka gudaha ee ku xidhan budada epoxy budada dibadda ee birta hal-lakabka ah ee polyetylen anticorrosive birta, gudaha dareeraha epoxy budada gudaha gudaha hal-lakab polyetylen anticorrosive birta, fiyuuska gudaha bonded epoxy budada dibadda saddex-lakab polyetylen ( 3PE) tuubo bir ah oo ka hortag ah, epoxy dareere gudaha ah (ipn8710) tubbada birta saddex-lakab ah ee dibadda ah
Halabuurka qaab dhismeedka epoxide gudaha ah iyo polyetylen-ka monolayer-ka ah
1. Maaddada saldhigga birta: tuubo bir ah oo aan kala go 'lahayn, tuubo bir ah oo koronto ah (alxan toosan, alxanka wareega)
2. Daahan gudaha ka-hortagga daxalka: isku-dhafka nadaafadda ee daahan budada epoxy-ga ah, isku-dhafka culus ee ka-hortagga daxalka ee ku xiran budada epoxy resin.

3. Daahan ka-hortagga daxalka ee dibadda: kulul oo dhalaalay daahan budada polyetylen-ka-lakab ah
Epoxide gudaha ah oo saddex-lakab ah oo polyetylen ah (3PE).
1. Maaddada saldhigga birta: tuubo bir ah oo aan kala go 'lahayn, tuubo bir ah oo koronto ah (alxan toosan, alxanka wareega)
2. Daahan gudaha ka-hortagga daxalka: isku-dhafka nadaafadda ee daahan budada epoxy-ga ah, isku-dhafka culus ee ka-hortagga daxalka ee ku xiran budada epoxy resin.
3.Daahan ka-hortagga daxalka ee dibadda: dhalaal kulul oo saddex-lakab ah oo polyetylen ah. Lakabka hoose waa fusion bonded budada resin epoxy, lakabka dhexe waa xabag kulul oo dhalaalaysa, lakabka sarena waa polyetylen cufnaanta sare leh.
Isbarbardhigga u dhexeeya Epoxide-ka gudaha monolayer PE iyo gudaha epoxide dibadda 3PE
Polyethylene iyo epoxy waxay leeyihiin iska caabin aad u fiican, laakiin mid kastaa wuxuu leeyahay faa'iidooyin u gaar ah. Polyethylene waa walxo heerkulbeeg ah oo leh dabacsanaan wanaagsan iyo iska caabin barar ah. Sababo la xiriira molecules non-polar, joogtaynta adhesion ee u dhexeeya polyetylen iyo tuubooyinka birta waa liidata; Xabagta Epoxy waa unug unug leh oo leh kooxo hydroxyl ah. Heerkul gaar ah, way fududahay in lagu falceliyo tuubooyinka birta waxayna leedahay dhejis adag. Si kastaba ha ahaatee, uma adkeyso isku dhaca sababtoo ah waa walax heerkulbeeye ah. Sidaa darteed, isku dhafka labada shay ayaa iska leh isku dhafka ugu fiican ee warshadaha ka hortagga daxalka.
Warshadaha tuubooyinka birta ee dahaarka leh ayaa laga soo saaray polyetylen-kii ugu horreeyay ee gudaha iyo dibedda ilaa epoxy gudaha iyo dibeddaba iyadoo ay ugu wacan tahay dhibaatooyinka adhesion, laakiin lakabka epoxy-ga dibadda uma adkeysto isku dhaca. Later, waxay u soo baxday jiilka saddexaad ee epoxy polyetylen dibadda ah, laakiin dhibaatada adhesion ayaa weli jirta marka polyetylen-ka-lakabka ah si toos ah loogu daro tuubada birta ah. Ugu dambayntii, waxa loo cusboonaysiiyay jiilka afraad ee ka-hortagga daxalka gudaha epoxy dibadda ee saddex-lakab ee polyetylen.
