NgakhalePVCNdi chitoliro chosakhala chachitsulo chomwe chimapezeka kwambiri padziko lonse lapansi, PPR (Polypropylene Random Copolymer) ndiye chitoliro chodziwika bwino m'madera ena ambiri padziko lapansi. Cholumikizira cha PPR si simenti ya PVC, koma chimatenthedwa ndi chida chapadera chosakanikirana ndipo chimasungunuka kukhala chonse. Ngati chipangidwa bwino ndi zida zoyenera, cholumikizira cha PPR sichidzatuluka madzi.

Tenthetsani chida cholumikizira ndikukonzekera payipi

Ikani soketi yoyenera pa chida cholumikizira.PPRZipangizo zowotcherera zimabwera ndi ma soketi awiriawiri a amuna ndi akazi a kukula kosiyanasiyana, omwe amafanana ndi mainchesi ofanana a mapaipi a PPR. Chifukwa chake, ngati mukugwiritsa ntchito chitoliro cha PPR chokhala ndi mainchesi 50 (mainchesi 2.0), sankhani manja awiri olembedwa 50 mm.

Zipangizo zolumikizira zogwira ndi manja nthawi zambiri zimatha kugwira ntchitoPPRmapaipi kuyambira 16 mpaka 63 mm (mainchi 0.63 mpaka 2.48), pomwe zitsanzo za benchi zimatha kugwira mapaipi osachepera 110 mm (mainchi 4.3).
Mungapeze mitundu yosiyanasiyana ya zida zolumikizira za PPR pa intaneti, mitengo yake ikuchokera pa US$50 mpaka kupitirira US$500.

Ikani chida cholumikizira kuti muyambe kutenthetsa soketi. Zida zambiri zolumikizira zimalumikizidwa mu soketi yokhazikika ya 110v. Chidacho chimayamba kutenthetsa nthawi yomweyo, kapena mungafunike kuyatsa switch yamagetsi. Ma model amasiyana, koma zingatenge mphindi zochepa kuti chidacho chitenthetse soketiyo kutentha kofunikira. [3]
Samalani kwambiri mukamagwiritsa ntchito chida cholumikizira kutentha ndipo onetsetsani kuti aliyense m'derali akudziwa kuti chikuyenda bwino komanso kutentha. Kutentha kwa soketi kumapitirira 250 °C (482 °F) ndipo kungayambitse kutentha kwambiri.

Dulani chitolirocho kutalika kwake ndi kudula kosalala komanso koyera. Chida cholumikizira chikatenthedwa, gwiritsani ntchito chida chothandiza kuyika chizindikiro ndikudula chitolirocho kutalika kofunikira kuti mupeze kudula koyera kolunjika ku shaft. Zida zambiri zolumikizira zimakhala ndi zodulira mapaipi zoyambira kapena zomangira. Zikagwiritsidwa ntchito motsatira malangizo, izi zipanga kudula kosalala, kofanana mu PPR, komwe ndikoyenera kwambiri pakulumikiza. [4]
Mapaipi a PPR amathanso kudulidwa ndi macheka osiyanasiyana amanja kapena macheka amagetsi kapena machubu odulira mapaipi okhala ndi mawilo. Komabe, onetsetsani kuti kudulako kuli kosalala komanso kofanana momwe mungathere, ndipo gwiritsani ntchito sandpaper yopyapyala kuti muchotse ma burrs onse.

Tsukani zigawo za PPR ndi nsalu ndi chotsukira chomwe chimalimbikitsidwa. Zida zanu zolumikizira zitha kulangiza kapena kuphatikiza chotsukira china chake cha chubu cha PPR. Tsatirani malangizo kuti mugwiritse ntchito chotsukirachi kunja kwa chitoliro ndi mkati mwa zolumikizira kuti zilumikizidwe. Lolani zidutswazo ziume kwa kanthawi. [5]
Ngati simukudziwa mtundu wa chotsukira chomwe mungagwiritse ntchito, chonde funsani wopanga chida chosakanikirana.

Ikani chizindikiro cha kuya kwa welding kumapeto kwa chitoliro. Chida chanu cholumikizira chingakhale ndi template yolembera kuya koyenera kwa weld pa mapaipi a PPR a mainchesi osiyanasiyana. Gwiritsani ntchito pensulo kuti mulembe chizindikiro cha chubu moyenerera.
Kapenanso, mutha kuyika tepi yoyezera mu fitting yomwe mukugwiritsa ntchito (monga fitting ya chigongono cha madigiri 90) mpaka itafika pa ridge yaying'ono mu fitting. Chotsani 1 mm (0.039 inchi) kuchokera muyeso wa kuya uku ndikuyika chizindikiro ngati kuya kwa weld pa chitoliro.

Tsimikizirani kuti chida cholumikizira chatenthedwa mokwanira. Zida zambiri zolumikizira zili ndi chowonetsera chomwe chimakuuzani nthawi yomwe chidacho chatenthedwa ndi yokonzeka. Kutentha komwe mukufuna nthawi zambiri kumakhala 260 °C (500 °F).
Ngati chida chanu cholumikizira magetsi chilibe chowonetsera kutentha, mungagwiritse ntchito probe kapena infrared thermometer kuti muwerenge kutentha komwe kuli pa soketi.
Mukhozanso kugula ndodo zosonyeza kutentha (monga Tempilstik) m'masitolo ogulitsa zinthu zowotcherera. Sankhani ndodo zamatabwa zomwe zimasungunuka pa 260 °C (500 °F) ndikukhudza imodzi pa soketi iliyonse.
