Mukuwona PE80 ndi PE100 pa ukadaulo. Manambalawa ndi osiyana, koma sizikudziwika bwino tanthauzo la izi pa polojekiti yanu. Kusokonezeka kumeneku kungayambitse kusankha njira yofooka kapena yokwera mtengo.

Kusiyana kwakukulu ndi mphamvu. PE100 ili ndi mphamvu yochepa yofunikira (MRS) yokwera ndi 25% kuposa PE80. Izi zimathandiza mapaipi a PE100 kukhala ndi makoma opyapyala okhala ndi mphamvu yofanana, zomwe zimapangitsa kuti akhale opepuka, otsika mtengo, komanso opatsa mphamvu yoyenda bwino.

Izi sizinthu zazing'ono chabe zaukadaulo; ndi kusintha kwakukulu kwa sayansi ya zinthu zomwe zili ndi ubwino waukulu. Monga wopanga, ndikukuuzani kutikusintha kuchokera ku PE80 kupita ku PE100Popeza muyezo wa makampani unali sitepe yofunika kwambiri. Woyang'anira kugula zinthu waluso ngati Arief ku Indonesia akumvetsa izi nthawi yomweyo. Amaona kuti PE100 imamulola kupereka ntchito yofanana ndi chinthu chogwira ntchito bwino, chopepuka, komanso chosavuta kuyika. Kusiyana pakati pa magiredi awiriwa kumakhudza chilichonse kuyambira bajeti ya polojekiti mpaka kudalirika kwa nthawi yayitali kwa dongosolo lonse.

Kodi chitoliro cha PE100 ndi chachikulu bwanji?

Mukufuna chitoliro cha polojekiti yanu, koma mukudabwa ngati PE100 imabwera mu kukula komwe mukufuna. Kusatsimikizika kumeneku kungapangitse kuti zikhale zovuta kutchula zida ndikukonzekera bwino chitoliro cha polojekiti yanu.

Chitoliro cha PE100 chikupezeka m'mitundu yosiyanasiyana ya kukula koyenera, kuyambira mainchesi ang'onoang'ono a 20mm mpaka mainchesi akuluakulu a 2500mm. PE100 ndi mtundu wa zinthu, osati kukula, kotero imatha kupangidwa pafupifupi mulingo uliwonse wofunikira pa ntchito iliyonse.

Mfundo yodziwika bwino yosokoneza ndi kuganiza kuti "PE100" ikutanthauza kukula. Ndikofunikira kukumbukira kuti PE100 ndiye mtundu wa zinthu. Ku fakitale yanga, timagwiritsa ntchito mtundu umodzi wochita bwino kwambiriwu kuti tipange mitundu yosiyanasiyana ya mapaipi. Timangosintha ma extrusion dies kuti tipange mapaipi kuyambira 20mm mpaka 800mm kapena kuposerapo. Ma diameter ang'onoang'ono, nthawi zambiri mpaka 110mm, amatha kuperekedwa muzozungulira zazitali, zomwe zimachepetsa kwambiri kuchuluka kwa malo olumikizirana omwe amafunikira poyika. Ma diameter akuluakulu amapangidwa molunjika, nthawi zambiri amakhala mamita 6 kapena 12 kutalika. Kukula komwe mukufuna kumapezeka mosavuta, chifukwa nsaluyo yokha ndi yosinthasintha kwambiri. Itha kusinthidwa kuti igwirizane ndi chilichonse kuyambira pa waya waung'ono wokhala m'nyumba mpaka paipi yayikulu yotumizira madzi m'matauni.

Kukula kwa Mapaipi Odziwika a PE100 ndi Kugwiritsa Ntchito

Cholimba ndi chiyani, PE kapena PVC?

Muyenera kusankha pakati pa PE ndi PVC, ndipo zonse ziwiri zimatchedwa "zolimba". N'zovuta kudziwa kuti ndi chinthu chiti chomwe chili cholimba komanso choyenera kwambiri pazofunikira za kukhazikitsa kwanu.

Zimatengera momwe mumafotokozera mphamvu. PVC ndi yolimba kwambiri ndipo imakhala ndi mphamvu yokoka kwambiri. Komabe, HDPE (PE) ndi yosinthasintha kwambiri ndipo imakhala ndi mphamvu yokoka kwambiri, makamaka nyengo yozizira. HDPE imatha kupindika ndikugunda zomwe zingaswe PVC.

Mainjiniya akamanena za "mphamvu," amatanthauza zinthu zosiyanasiyana. PVC ndi yolimba kwambiri. Izi zikutanthauza kuti imakana kupindika, zomwe zingakhale zothandiza pazinthu zina zomwe sizikufuna kuti chitolirocho chigwedezeke. Komabe, kulimba komweku kumapangitsa PVC kukhala yofooka. Kugundana kwakukulu kuchokera ku mwala panthawi yodzaza, kapena ngakhale kugwetsedwa panthawi yozizira, kungayambitse kusweka kapena kusweka. HDPE ndi yosiyana. Ndi yosinthasintha ndipo ili ndi zodabwitsakukana kukhudzidwa. Mutha kuyimenya ndi nyundo, ndipo mwina ingangopindika. Kulimba kumeneku kumapangitsa kuti ikhale yolekerera kwambiri panthawi yoyiyika komanso yolimba kwambiri pa mapaipi obisika. Imatha kusinthasintha ndi kayendedwe ka nthaka kapena nthaka ikakhazikika popanda kusweka, zomwe ndi zabwino kwambiri kuti ikhale yodalirika kwa nthawi yayitali.

Mphamvu Zake: HDPE vs. PVC

Nchifukwa chiyani mumagwiritsa ntchito HDPE kuposa PVC?

Mukuona kuti PVC nthawi zambiri imakhala yotsika mtengo komanso imapezeka mosavuta. Mukudabwa chifukwa chake wina angasankhe HDPE. Popanda kuwona ubwino wake, kugwiritsa ntchito HDPE kungawoneke ngati ndalama zowonjezera zosafunikira.

Gwiritsani ntchito HDPE kuposa PVC chifukwa cha malo ake olumikizirana omwe salola kutuluka kwa madzi, kusinthasintha kwabwino, komanso kulimba kwambiri. Zinthuzi zimapangitsa kuti ikhale yabwino kwambiri poyiyika popanda ngalande, yolimba kusuntha kwa nthaka, komanso yankho lodalirika kwambiri lomwe limachotsa kutaya madzi kuchokera kumalo olumikizirana omwe amatuluka madzi.

Chifukwa chachikulu chosankhira HDPE ndi njira yolumikizira. Mapaipi a HDPE ndikuphatikizana ndi kutentha, yomwe imasungunula malekezero a chitoliro pamodzi kuti apange pulasitiki imodzi yokhazikika, ya monolithic. Cholumikiziracho ndi cholimba ngati chitolirocho ndipo sichidzataya madzi. PVC imadalira ma gasket kapena simenti yosungunulira, zomwe zimapangitsa kuti pakhale malo ofooka mumzere womwe ungawonongeke pakapita nthawi. Kwa ogwira ntchito zamadzi, zolumikizira izi zotayikira madzi ndi gwero lalikulu la kutaya madzi. Chachiwiri ndi kusinthasintha. Kusinthasintha kwa HDPE kumalola kuti iikidwe ndiukadaulo wopanda migero monga kuboola molunjika mopingasa (HDD)Izi zikutanthauza kuti mutha kuyika payipi pansi pa mtsinje kapena msewu wotanganidwa popanda kukumba ngalande yayikulu. Izi zimapulumutsa nthawi ndi ndalama zambiri pakufukula ndi kukonzanso. Ubwino uwu umapereka phindu la nthawi yayitali lomwe limaposa kusiyana kulikonse koyambirira kwa mtengo wazinthu.

Ubwino Waukulu wa HDPE vs. PVC

Kodi mungamamatire HDPE ku PVC?

Muyenera kulumikiza chitoliro chatsopano cha HDPE ku chingwe cha PVC chomwe chilipo kale. Muli ndi guluu wa PVC pafupi, koma simukudziwa ngati ugwira ntchito. Kugwiritsa ntchito njira yolakwika yolumikizira kungayambitse kutuluka kwa madzi ambiri.

Ayi, simungathe kumata HDPE ku PVC. Mphamvu za mankhwala a HDPE zimaletsa simenti iliyonse yosungunulira (guluu) kuti isagwirizane ndi pamwamba pake. Kuti mulumikize zinthu ziwirizi, muyenera kugwiritsa ntchito cholumikizira chamakina monga cholumikizira cha flange kapena cholumikizira chapadera chosinthira.

Chifukwa chomwe simungamamatire HDPE ndi chifukwa chomwechi chomwe chimalimbana ndi mankhwala. Kapangidwe kake ka molekyulu ndi kokhazikika kwambiri komanso kosakhala ndi polar, zomwe zikutanthauza kuti zosungunulira zimangotuluka pamwamba popanda kukhudza. Guluu wa PVC umagwira ntchito posungunula pamwamba pa PVC mwa mankhwala kotero kuti umalumikizana. Njirayi sigwira ntchito pa HDPE. Njira yokhayo yolondola komanso yodalirika yolumikizira zinthu ziwirizi ndi kugwiritsa ntchito makina olumikizira. Njira yodziwika kwambiri ndikugwiritsa ntchito ma flange. Timalumikiza matako ndiAdaputala ya flange ya HDPE (yomwe imatchedwanso mapeto a stub)ku chitoliro cha HDPE. Kenako mumamatira flange ya PVC pa chitoliro cha PVC. Pomaliza, mumalumikiza ma flange awiriwa pamodzi ndi gasket ya rabara pakati kuti mupange chisindikizo chosalowa madzi. Ndi njira yosavuta, yolimba, komanso yotetezeka yomwe timapereka zolumikizira nthawi zonse.

Mapeto

Kusiyana pakati pa PE80 ndi PE100 ndi mphamvu, pomwe PE100 ndi yabwino kwambiri. HDPE ndi yolimba komanso yosinthasintha kuposa PVC, yolumikizidwa ndi fusion yosatulutsa madzi, ndipo iyenera kulumikizidwa ndi makina.
