1. Kev Ntseeg: Peb muaj cov xim ntsuab thiab dawb ppr, tab sis muaj coob tus neeg xav tias dawb yog qhov zoo, qhov tseeb nws tsis yog qhov teeb meem, tsis muaj kev sib raug zoo nrog cov xim tha xim. PPR tubing yog qhov ua kom tsis zoo kiag thiab zoo heev, nrog me ntsis teeb lossis ib nrab pob tshuam ntawm kub me ntsis. Thiab tseem yuav xyuas seb puas muaj npuas, kev nyuaj siab, grooves thiab impurities thiab lwm yam tsis xws luag.
2.Qhov: Kev ntxhib los mos, zoo siab PPR yeeb yam ntshiab qauv, tsis muaj lwm yam ntaub ntawv, ntsa du, zoo zoo; Yog hais tias qhov xav tias tsis zoo, nws yuav yog impurities hauv cov khoom, cov yeeb nkab no tej zaum tsis zoo heev.
3.Smell: Hnov, cov khoom tseem ceeb yog polypropylene PPR yeeb nkab, yog tias cov yeeb nkab tsis ntxhiab, me ntsis sib txawv yuav muaj ib tug saj, qhov no yog vim yog lub admixture ntawm polyethylene.
4.Pinch: hardness, yog hais tias ib lub PPR raj tau yooj yim pinch deformation, qhov no yeej tsis yog pure ntshiab PPR raj, vim tus PPR raj zoo yog qhov nyuaj.
5. Ntsuas: phab ntsa tawv, yog hais tias koj tso cai rau daim ntawv tso cai, koj siv tau tus vipier caliper los ntsuas cov phab ntsa ntawm lub pob zeb yog cov txheej txheem thiab tus qauv, tiam sis siv hom no, peb yuav tsum xub nkag siab lub PPR raj ntawm lub tebchaws no ntau npaum li cas.
6.Tsis mloog: suab nrov, PPR raj xa mus rau lub caij nplooj ntoos zeeg dawb, tsaws suab yog qhov tho txawv yog PPR raj, yog lub suab sib txawv, nws yog PPR raj zoo.
7.Hit: elasticity, ntawm no tsis yog hais tias smashing, smashing rotted yeeb nkab yog ib tug yeeb nkab zoo, ntawm no kom pom tias lub elasticity, resilience thiab zoo zoo yog PPR, tab sis qhov kub yog tsawg dua 10 degrees nrog hom no, lub zoo yeeb nkab yuav tsoo.
8. Kev haus luam yeeb: tsis hnov tsw pa luam yeeb hlawv hlawv, nws tuaj yeem hlais cov yeeb nkab thiab hlawv, yog tias tom qab cov pa luam yeeb dub thiab pungent tsw, tsis zoo rau PPR yeeb nkab, PPR yeeb nkab zoo, yuav tsis muaj pa luam yeeb dub thiab hlawv hnov tsw, lub melting ntawm lub kua yog tseem huv heev.
9. Lub thauv: vuam PPR yeeb nkab, qhov ntsuas qhov kub ntawm qhov nruab nrab yog 260 thiab 290 degrees, pom tias cov raj hauv lub cev deformation, yeeb nkab fittings seb yog nqus, zoo PPR raj tsis yog daim duab, lub puab diam iav tsis yooj yim rau deformation .
