Iintambo eziBambelela ilangatye

Iintambo ezithintela ilangatye ziintambo ezenzelwe ngokukodwa ezinezinto zokwakha ezilungiselelwe ukumelana nokusasazeka kwamalangatye xa kutsha. Ezi ntambo zithintela ilangatye ukuba lingasasazeki kubude bentambo kwaye zinciphise ukukhutshwa komsi kunye neegesi ezinobungozi xa kutsha. Zisetyenziswa kakhulu kwiindawo apho ukhuseleko lomlilo lubaluleke kakhulu, njengezakhiwo zikawonke-wonke, iinkqubo zothutho, kunye nezakhiwo zoshishino.

Iintlobo zezinto ezisetyenziswa kwiintambo ezithintela umlilo

Iileya zepolymer zangaphandle nezangaphakathi zibaluleke kakhulu kwiimvavanyo zokuthintela umlilo, kodwa uyilo lwentambo luhlala luyinto ebaluleke kakhulu. Intambo eyakhiwe kakuhle, esebenzisa izixhobo ezifanelekileyo zokuthintela umlilo, inokufezekisa ngempumelelo iipropati zokusebenza komlilo ezifunekayo.

Iipolymers ezisetyenziswa rhoqo kwizicelo ezithintela umlilo ziqukaI-PVCkwayeI-LSZHZombini zenziwe ngokukodwa ngezongezo ezithintela umlilo ukuze zihlangabezane neemfuno zokhuseleko lomlilo.

Uvavanyo oluBalulekileyo lwezinto ezithintela ilangatye kunye nophuhliso lwentambo

I-Limiting Oxygen Index (LOI): Olu vavanyo lulinganisa ubuncinci boxinzelelo lweoksijini kumxube weoksijini kunye ne-nitrogen eya kuxhasa ukutsha kwezinto, ezichazwe njengepesenti. Izinto ezine-LOI engaphantsi kwama-21% zihlelwa njengezinokutsha, ngelixa ezo zine-LOI engaphezulu kwama-21% zihlelwa njengezizicimayo. Olu vavanyo lubonelela ngokuqonda okukhawulezileyo nokusisiseko kokutsha. Imigangatho esebenzayo yi-ASTMD 2863 okanye i-ISO 4589

I-Cone Calorimeter: Esi sixhobo sisetyenziselwa ukuqikelela indlela umlilo oza kwenzeka ngayo ngexesha langempela kwaye sinokumisela iiparameter ezifana nexesha lokutsha, izinga lokukhululwa kobushushu, ukulahleka kobunzima, ukukhululwa komsi, kunye nezinye iimpawu ezinxulumene neempawu zomlilo. Imigangatho ephambili esebenzayo yi-ASTM E1354 kunye ne-ISO 5660, i-Cone calorimeter inika iziphumo ezithembekileyo ngakumbi.

Uvavanyo lokukhupha igesi ye-asidi (IEC 60754-1). Olu vavanyo lulinganisa umxholo wegesi ye-asidi ye-halogen kwiintambo, lumisela ubungakanani be-halogen ekhutshwayo ngexesha lokutsha.

Uvavanyo lweGesi Corrositvity (IEC 60754-2). Olu vavanyo lulinganisa i-pH kunye nokuqhuba kwezinto ezibolayo

Uvavanyo loxinano lomsi okanye uvavanyo lwe-3m3 (IEC 61034-2). Olu vavanyo lulinganisa uxinano lomsi oluveliswa ziintambo ezitshayo phantsi kweemeko ezichaziweyo. Uvavanyo lwenziwa kwigumbi elinobukhulu beemitha ezi-3 ngemitha ezi-3 ngemitha ezi-3 ngemitha ezi-3 (yiyo loo nto kuthiwa luvavanyo lwe-3m³) kwaye lubandakanya ukujonga ukuncipha kokudluliselwa kokukhanya ngomsi oveliswa ngexesha lokutsha.

Uvavanyo loxinano lomsi (SDR) (ASTMD 2843). Olu vavanyo lulinganisa uxinano lomsi oluveliswa kukutsha okanye ukubola kweplastiki phantsi kweemeko ezilawulwayo. Uvavanyo lobungakanani besampulu 25 mm x 25 mm x 6 mm
