Urajijinganyije n'uburyo bwose bwo gushyiramo pulasitiki? Guhitamo ikintu kibi bishobora gutera gutinda kw'umushinga, kuva amazi, no gusana bihenze. Gusobanukirwa ibikoresho bya PP ni ingenzi mu guhitamo igice gikwiye.

Ibikoresho bya PPni imiyoboro ikoze muri polypropylene, thermoplastic ikomeye kandi ikoreshwa mu buryo butandukanye. Ikoreshwa cyane cyane mu guhuza imiyoboro mu buryo busaba kwihanganira ubushyuhe bwinshi no kurwanya imiti, bigatuma iba nziza cyane mu nganda, muri laboratwari no mu mazi ashyushye.

Naherutse guhamagara Budi, umuyobozi ushinzwe kugura muri Indoneziya. Ni inzobere muri PVC ariko hari umukiriya mushya wasabye “Ibikoresho byo gukanda PP"Ku bijyanye no kuvugurura laboratwari. Budi ntiyari azi neza itandukaniro rikomeye n'igihe cyo gutanga inama ku birebana na PP kurusha PVC nk'uko yari abizi neza. Yari afite impungenge zo gutanga inama zitari zo. Ibi ni ibisanzwe. Inzobere nyinshi zizi ubwoko bumwe cyangwa bubiri bw'ibikoresho byo gufunga imiyoboro ariko amoko menshi ya plastiki aragoye. Kumenya imbaraga zihariye z'ibikoresho nka polypropylene nibyo bitandukanya umucuruzi woroshye n'umutanga serivisi. Reka turebe icyatuma ibikoresho bya PP biba ingenzi mu miyoboro igezweho y'amazi.

Igikoresho cyo gushyiramo PP ni iki?

Ugomba guhuza imiyoboro kugira ngo ubone akazi gakomeye, ariko ntuzi neza niba PVC ishobora kubyitwaramo. Gukoresha ibikoresho bitari byo byanze bikunze bizatuma sisitemu inanirwa kandi ihindurwe ihenze.

Igikoresho cya PP gishyirwamo ibikoresho bihuza ibintu gikozwe muri pulasitiki ya polypropylene. Ibiranga by'ingenzi ni ugukomera mu bushyuhe bwinshi (kugeza kuri 180°F cyangwa 82°C) no kurwanya aside, alkali, n'ibindi bintu bihumanya, niyo mpamvu gitoranywa kuruta PVC isanzwe mu duce runaka.

Iyo turebye neza ibijyanye no gushyira PP, tuba tureba imiterere ya polypropylene ubwayo.PVC, ishobora kwangirika bitewe n’imiti imwe n’imwe cyangwa igahinduka iyo ubushyuhe buri hejuru, PP ikomeza imiterere yayo. Ibi bituma iba ibikoresho byo gukoresha mu bintu nk’imiyoboro y’imyanda ya shimi muri laboratwari ya kaminuza cyangwa imiyoboro y’amazi ashyushye mu nyubako y’ubucuruzi. Nasobanuriye Budi ko nubwo PVC naIbikoresho bya PPGuhuza imiyoboro, akazi kayo karatandukanye cyane. Ukoresha PVC mu miyoboro y'amazi akonje muri rusange. Ukoresha PP iyo hari ubushyuhe cyangwa imiti. Yahise abyumva. Ntabwo ari "ikintu cyiza" kirimo, ahubwo ni ikiigikoresho gikwiyeku kazi runaka umukiriya we akeneye gukora.

Ibikoresho bya PP ugereranije na PVC: Igereranya ryihuse

Kugira ngo amahitamo arusheho kuba meza, dore incamake yoroheje y'aho buri gikoresho kimurika.

PP isobanura iki mu bijyanye no gupima imiyoboro?

Ubona inyuguti "PP" muri kataloge y'ibicuruzwa, ariko se koko bivuze iki kuri sisitemu yawe? Kwirengagiza kode z'ibikoresho bishobora gutuma ugura ibicuruzwa bitakubereye.

Mu miyoboro, PP isobanura Polypropylene. Ni izina rya polymer ya thermoplastic ikoreshwa mu gukora umuyoboro cyangwa igipfunyika. Iki kirango kikwereka ko ibicuruzwa byubatswe kugira ngo birambe, birwane n'imiti, kandi bikore neza mu bushyuhe buri hejuru, bikitandukanya n'ibindi bikoresho bya pulasitiki nka PVC cyangwa PE.

Polypropylene ni kimwe mu bigize umuryango w'ibikoresho byitwathermoplasticsMu magambo make, ibi bivuze ko ushobora kubishyushya kugeza aho bishongesha, ukabikonjesha, hanyuma ukongera kubishyushya nta kwangirika gukomeye. Iyi miterere ituma byoroha kubikora mu buryo bugoye nka tee-fittings, equors, na adapters binyuze mu gusya inshinge. Ku mucungamutungo nka Budi, kumenya "PP" bivuze ko polypropylene ari yo ntambwe ya mbere. Igikurikiraho ni ukumenya ko hari ubwoko butandukanye bwa PP. Ebyiri zikunze kugaragara niPP-H(Homopolymer) na PP-R (Random Copolymer). PP-H irakomeye cyane kandi ikunze gukoreshwa mu nganda. PP-R iraryoshye kandi niyo ikoreshwa mu miyoboro y'amazi ashyushye n'akonje mu nyubako. Ubu bumenyi bumufasha kubaza abakiriya be ibibazo byiza kugira ngo barebe neza ko babona umusaruro nyawo bakeneye.

Ubwoko bwa Polypropylene mu miyoboro

Umuyoboro wa PP ni iki?

Ukeneye umuyoboro w'amazi ashyushye cyangwa imiyoboro y'imiti kandi wifuza kwirinda kwangirika kw'ibyuma. Guhitamo imiyoboro mibi bishobora gutera umwanda, amazi akava, ndetse no kumara igihe gito ubikora.

Umuyoboro wa PP ni umuyoboro ukozwe muri pulasitiki ya polypropylene, wagenewe gutwara amazi ashyushye, amazi meza, n'ibindi binyabutabire bitandukanye mu buryo bwizewe. Ni woroshye, ntugwa ingese, kandi utanga ubuso bworoshye imbere burwanya ubwiyongere bw'ibipimo, bigatuma amazi atemba neza uko igihe kigenda.

Imiyoboro ya PP ikoreshwa hamwe n'ibikoresho bya PP kugira ngo habeho sisitemu yuzuye kandi ihuye. Kimwe mu byiza bikomeye ni uburyo ihuzwa. Hakoreshejwe uburyo bwitwagusudira ubushyuhe, umuyoboro n'icyuma bishyushya kandi bigahuzwa burundu. Ibi bituma habaho ikintu gikomeye,ingingo idatobokaikomeye nk'umuyoboro ubwawo, ikuraho intege nke ziboneka muri sisitemu za kole (PVC) cyangwa inyuzi (ibyuma). Nigeze gukorana n'umukiriya ku ruganda rushya rutunganya ibiribwa. Bahisemo icyuma cyuzuyeSisitemu ya PP-Rku mazi ashyushye n'imiyoboro yo gusukura. Kuki? Kubera ko ibikoresho bitashoboraga kwinjiza imiti iyo ari yo yose mu mazi, kandi ingingo zahujwe zasobanuraga ko nta myenge yari ihari kugira ngo bagiteri zikure. Ibi byatumye umusaruro wabo urushaho kuba mwiza kandi umutekano w'imikorere yabo ukaba mwiza. Kuri bo, inyungu z'imiyoboro ya PP zarenze imiyoboro yoroshye; byari ikibazo cyo kugenzura ubuziranenge.

Ibikoresho bya PB ni iki?

Ukumva ibyerekeye ibikoresho bya PB ukibaza niba ari ubundi buryo bwo gusimbura PP. Guvanga ibi bikoresho byombi bishobora kuba ikosa rikomeye, kuko umuntu afite amateka yo gutsindwa gukabije.

Ibikoresho bya PB ni imiyoboro ihuza imiyoboro ya Polybutylene (PB), ibikoresho byoroshye byo gushyiramo imiyoboro byahoze bikoreshwa mu miyoboro yo mu ngo. Bitewe n'ingaruka nyinshi zo kwangirika kw'imiti, imiyoboro ya PB n'ibiyikoreshwamo ntabwo byemewe n'amategeko menshi agenga imiyoboro kandi bifatwa nk'ibishaje kandi bidakwiye kwizerwa.

Iyi ni ingingo y'ingenzi y'uburezi ku muntu wese uri mu nganda. Nubwo PP (Polypropylene) ari ibikoresho bigezweho kandi byizewe, PB (Polybutilene) niyo yabanjirije iyi ngaruka mbi. Kuva mu myaka ya 1970 kugeza mu myaka ya 1990, PB yashyizwe cyane ku miyoboro y'amazi ashyushye n'akonje. Ariko, byagaragaye ko imiti isanzwe mu mazi ya komini, nka chlorine, yibasiye polybutylene n'ibikoresho byayo bya pulasitiki, bituma bicika intege. Ibi byatumye habaho imiyoboro itunguranye n'amazi asohoka nabi, bigatera kwangirika kwa miliyari z'amadolari mu ngo zitabarika. Iyo Budi abonye ubusabe rimwe na rimwe bwo gukoresha ibikoresho bya PB, akenshi biba ari ibyo gusanwa. Namutoje guhita agira inama umukiriya ku ngaruka za sisitemu yose ya PB no gutanga inama yo gusimbuza ibikoresho bihamye kandi bigezweho nkaPP-R or PEXNtabwo ari ukugira ngo haboneke igurishwa rinini, ahubwo ni ukugira ngo habeho kurinda umukiriya gutsindwa mu gihe kizaza.

Polypropylene (PP) ugereranije na Polybutylene (PB)

Umwanzuro

Ibikoresho bya PP, bikozwe muri polypropylene iramba, ni byo bikunze gukoreshwa mu gukoresha amazi ashyushye n'imiti. Ni igisubizo kigezweho kandi cyizewe, bitandukanye n'ibikoresho bishaje kandi byangiritse nka polybutylene.
