NgakhaleZithunzi za PVCndi chitoliro wamba sanali zitsulo padziko lonse, PPR (Polypropylene Random Copolymer) ndi muyezo chitoliro zakuthupi m'madera ena ambiri a dziko. Cholumikizira cha PPR si simenti ya PVC, koma chimatenthedwa ndi chida chapadera chophatikizira ndipo chimasungunuka kwathunthu. Ngati zidapangidwa moyenera ndi zida zoyenera, cholumikizira cha PPR sichingadutse.

Kutenthetsa chida chophatikizira ndikukonzekera payipi

Ikani socket yoyenera pa chipangizo chophatikizira. AmbiriPPRzida zowotcherera zimabwera ndi ma socket aamuna ndi aakazi amitundu yosiyanasiyana, omwe amafanana ndi ma diameter wamba a PPR. Choncho, ngati mukugwiritsa ntchito PPR chitoliro ndi awiri a 50 mm (2.0 mainchesi), kusankha awiri a manja chizindikiro 50 mm.

Zida zophatikizira pamanja zimatha kugwira ntchitoPPRmapaipi kuyambira 16 mpaka 63 mm (0.63 mpaka 2.48 mainchesi), pomwe ma benchi amatha kunyamula mapaipi osachepera 110 mm (4.3 mainchesi).
Mutha kupeza mitundu yosiyanasiyana ya zida zophatikizira za PPR pa intaneti, zokhala ndi mitengo kuyambira pafupifupi US$50 mpaka kupitilira US$500.

Lowetsani chida chophatikizira kuti muyambe kutentha soketi. Zida zambiri zophatikizira zimalumikiza socket yokhazikika ya 110v. Chidacho chidzayamba kutentha nthawi yomweyo, kapena mungafunike kuyatsa chosinthira magetsi. Zitsanzo zimasiyana, koma zingatenge mphindi zingapo kuti chida chiwotche soketi kuti ikhale yofunikira kutentha. [3]
Samalani kwambiri mukamagwiritsa ntchito chida chophatikizira chamafuta ndikuwonetsetsa kuti aliyense mderali akudziwa kuti ikuyenda komanso yotentha. Kutentha kwa soketi kumapitilira 250 ° C (482 ° F) ndipo kumatha kupsa kwambiri.

Chepetsani chitolirocho kuti chikhale chachitali ndi chodula choyera. Chida chophatikizira chikatenthedwa, gwiritsani ntchito chida chothandizira kuyika chizindikiro ndikudula chitolirocho mpaka kutalika kofunikira kuti mupeze chodulidwa choyera chokhazikika patsinde. Zida zambiri zophatikizira zimakhala ndi zida zoyambira kapena zodulira mapaipi. Akagwiritsidwa ntchito molingana ndi malangizo, izi zimapanga chodulidwa chosalala, yunifolomu mu PPR, yomwe ili yoyenera kwambiri kuwotcherera. [4]
Mapaipi a PPR amathanso kudulidwa ndi macheka osiyanasiyana am'manja kapena macheka amagetsi kapena odula mapaipi amawilo. Komabe, onetsetsani kuti chodulidwacho ndi chosalala komanso chotheka, ndipo gwiritsani ntchito sandpaper yabwino kuchotsa ma burrs onse.

Tsukani zigawo za PPR ndi nsalu ndi zotsukira zovomerezeka. Zida zanu zophatikizira zitha kupangira kapena kuphatikiza zotsukira za PPR chubu. Tsatirani malangizo oti mugwiritse ntchito chotsukirachi kunja kwa chitoliro ndi mkati mwa zolumikizira kuti zilumikizidwe. Siyani zidutswazo ziume kwa kanthawi. [5]
Ngati simukudziwa kuti ndi mtundu wanji wa zotsukira zomwe mungagwiritse ntchito, chonde lemberani wopanga zida zophatikizira.

Lembani kuya kwa kuwotcherera kumapeto kwa kugwirizana kwa chitoliro. Chida chanu chophatikizira chikhoza kubwera ndi template yolembera kuzama koyenera pa mapaipi a PPR a ma diameter osiyanasiyana. Gwiritsani ntchito pensulo kuti mulembe chubu moyenerera.
Kapenanso, mutha kuyika muyeso wa tepi muzoyenera zomwe mukugwiritsa ntchito (monga 90-degree elbow fitting) mpaka itagunda kamtunda kakang'ono koyenera. Chotsani 1 mm (0.039 inchi) kuchokera muyeso wakuzama uku ndikuyika chizindikiro ngati kuya kwa weld pa chitoliro.

Tsimikizirani kuti chida chophatikizira chatenthedwa kwathunthu. Zida zambiri zophatikizira zimakhala ndi chiwonetsero chomwe chimakuwuzani chidacho chikatenthedwa ndikukonzekera. Kutentha koyembekezeka kumakhala 260 °C (500 °F).
Ngati chida chanu chophatikizira chilibe chowonetsera kutentha, mutha kugwiritsa ntchito probe kapena thermometer ya infrared kuti muwerenge kutentha pa soketi.
Mukhozanso kugula ndodo zosonyeza kutentha (mwachitsanzo Tempilstik) m'masitolo ogulitsa zowotcherera. Sankhani timitengo tomwe tisungunuke pa 260 °C (500 °F) ndikukhudza imodzi pa soketi iliyonse.
