Kwaguka Kugera Kumurongo wa Plastike

Nubwo rimwe na rimwe ububiko bwa pulasitike bugaragara nkibicuruzwa byihariye - guhitamo kwambere mubakora cyangwa bashushanya ibicuruzwa biva mu mashanyarazi ya sisitemu yinganda cyangwa bagomba kuba bafite ibikoresho bisukuye cyane - tuvuge ko iyi mibande idafite imikoreshereze rusange muri rusange ni ngufi- kureba. Mubyukuri, ububiko bwa plastike uyumunsi bufite uburyo butandukanye bwo gukoresha nkubwoko bwagutse bwibikoresho hamwe nabashushanya neza bakeneye ibyo bikoresho bisobanura inzira nyinshi kandi nyinshi zo gukoresha ibyo bikoresho bitandukanye.

UMUTUNGO WA PLASTIC
Ibyiza bya plaque ya plastike ni binini - kwangirika, imiti no kurwanya abrasion; imbere imbere y'urukuta; uburemere bworoshye; koroshya kwishyiriraho; kuramba; no kugabanya ubuzima bwikurikiranya. Izi nyungu zatumye abantu benshi bemera ububiko bwa plastike mubikorwa byubucuruzi ninganda nko gukwirakwiza amazi, gutunganya amazi mabi, gutunganya ibyuma n’imiti, ibiryo na farumasi, amashanyarazi, uruganda rutunganya amavuta nibindi.
Ibikoresho bya plastiki birashobora gukorwa mubikoresho byinshi bitandukanye bikoreshwa muburyo butandukanye. Indangantego ya plastike ikunze gukorwa muri polyvinyl chloride (PVC), chlorine polyvinyl chloride (CPVC), polypropilene (PP), na fluoride polyvinylidene (PVDF). Indangantego za PVC na CPVC zisanzwe zifatanije na sisitemu yo kuvoma hakoreshejwe umusemburo wa sima wa sock, cyangwa ududodo twiziritse; mugihe, PP na PVDF bisaba guhuza ibice bya sisitemu, haba mubushuhe-, buto- cyangwa tekinoroji ya electro-fusion.

Nubwo polypropilene ifite kimwe cya kabiri cyimbaraga za PVC na CPVC, ifite imiti myinshi irwanya imiti kuko ntamuti uzwi. PP ikora neza muri acide yibanze ya acide na hydroxide, kandi irakenewe kandi kubisubizo byoroheje bya acide nyinshi, alkalis, umunyu hamwe nimiti myinshi kama.

PP irahari nkibintu bifite pigment cyangwa idafite pigment (naturel). PP karemano yangiritse cyane nimirasire ya ultraviolet (UV), ariko ibice birimo ibice birenga 2,5% bya karubone yumukara wa pigmentation UV ihagaze neza.

Sisitemu yo kuvoma PVDF ikoreshwa mubikorwa bitandukanye byinganda kuva muri farumasi kugeza mu bucukuzi bw'amabuye y'agaciro kubera imbaraga za PVDF, ubushyuhe bwakazi hamwe n’imiti irwanya imyunyu, acide ikomeye, ibishingwe byangiza hamwe n’imashanyarazi myinshi. Bitandukanye na PP, PVDF ntabwo yangizwa nizuba; icyakora, plastike ibonerana urumuri rwizuba kandi irashobora kwerekana amazi kumirasire ya UV. Mugihe uburyo busanzwe bwa PVDF budasanzwe, butagira isuku cyane mubisabwa mu nzu, wongeyeho pigment nkumutuku wo mu rwego rwibiryo byemerera guhura nizuba ryizuba nta ngaruka mbi bigira kumazi.
