Musiyano pakati pe polyethylene tambo uye polypropylene tambo

Munguva pfupi yapfuura, mutengi akabvunza nezve mutengo wePP danline tambo.Mutengi mugadziri anotumira mambure ekuredza kunze kwenyika.Kazhinji, vanoshandisa tambo yepolyethylene.Asi tambo yepolyethylene inonyanya kupfava uye yakanaka uye iri nyore kusunungura mushure mekuputira.Kubatsira kwePP danline tambo ndeye fiber yayo chimiro.Fiber yacho inenge yakaoma uye pfundo racho haritsvedzi.

Tichifunga, iyo molecular formula yepropylene ndeye: CH3CH2CH3, uye iyo molecular formula ye ethylene ndeye: CH3CH3.

Chimiro che polypropylene ndeichi:

— (CH2-CH (CH3) -CH2-CH (CH3) -CH2-CH (CH3)) n —-

Chimiro che polyethylene ndeichi:

— (CH2-CH2-CH2-CH2) n —-

Inogona kuonekwa kubva kune chimiro kuti polypropylene ine rimwe rebazi cheni kupfuura polyethylene.Mushure mekunge tambo yagadzirwa, nekuda kwebasa reketani yebazi, tambo yepolypropylene ine simba rakasimba rekusimba kupfuura polyethylene uye knot haisi kutsvedza.

Tambo yepolyethylene inochinjika uye yakatsetseka kupfuura polypropylene, uye inonzwa yakapfava.

Density ye polypropylene i 0.91, uye density ye polyethylene i 0.93.Saka Tambo yePE inorema kudarika tambo yePP.
