Ubumenyi bwibanze bwubwoko butatu bwibikoresho bya PE (II)

3. LLDPE

LLDPE ntabwo ari uburozi, uburyohe kandi nta mpumuro nziza, kandi ubucucike buri hagati ya 0.915 na 0.935g / cm3.Ni kopolymer ya Ethylene hamwe nigipimo gito cyo mu rwego rwo hejuru α-olefin ikorwa na catalizator, ikaba ikozwe na polymer yumuvuduko mwinshi cyangwa umuvuduko muke.Imiterere ya molekuline isanzwe ya LLDPE irangwa numurongo wumugongo wacyo ufite amashami maremare cyangwa maremare, ariko arimo amashami magufi.Kubura kw'amashami maremare atuma polymer iba kristaline.

Ugereranije na LDPE, LLDPE ifite ibyiza byimbaraga nyinshi, gukomera kwiza, gukomera gukomeye, kurwanya ubushyuhe no kurwanya ubukonje.

Vuga muri make

Muncamake, ibikoresho bitatu byavuzwe haruguru bikina imirimo yingenzi muburyo butandukanye bwimishinga yo kurwanya seepage.HDPE, LDPE na LLDPE byose bifite insulente nziza, bitarinda ubushuhe hamwe na anti-seepage, kandi imitungo yabo idafite uburozi, uburyohe kandi idafite impumuro nziza ituma ikoreshwa cyane mubuhinzi, ubworozi bw'amafi, ibiyaga byubukorikori, ibigega, ninzuzi, kandi byabaye imbaraga. yazamuwe kandi ikwirakwizwa na Biro y’Uburobyi muri Minisiteri y’Ubuhinzi y’Ubushinwa, Ishuri ry’Ubumenyi bw’Uburobyi bwa Shanghai, n’Ikigo cy’imashini n’uburobyi.

Mubidukikije biciriritse bya acide ikomeye, base base, okiside ikomeye na organic solvent, ibintu bifatika bya HDPE na LLDPE birashobora gukoreshwa neza no gukoreshwa, cyane cyane imitungo ya HDPE mukurwanya aside ikomeye, alkali, okiside ikomeye hamwe na solge organic.Ibice birarenze cyane kubindi bikoresho bibiri, bityo HDPE anti-seepage hamwe na coil anti-ruswa yakoreshejwe rwose munganda zikora imiti n’ibidukikije.

LDPE ifite kandi aside nziza, alkali, ibiranga igisubizo cyumunyu, kandi ifite kwaguka neza, kubika amashanyarazi, gutuza imiti, gutunganya no kurwanya ubushyuhe buke, bityo ikoreshwa mubuhinzi, ubworozi bw'amafi, gupakira, cyane cyane ikoreshwa cyane mubipfunyika ubushyuhe buke n'ibikoresho by'insinga.

Uwitekaimashini zisohora plastikebikozwe na KHMC cyane cyane ukoreshe HDPE mugukora umugozi wa monofilament.Umugozi wa plastiki wakozwe na mashini yacu ufite imbaraga nyinshi kandi nziza cyane.
