Я тут все о своем больном. Выявил методом тыка некоторые закономерности. Практически все виды пнд, он же hdpe, размягчаются органическими растворителями {ацетон, бензин, этилацетат итд) в смеси с полихлоропреновыми клеями. Чистые растворители никакого влияния не оказывают. Даже бутылки из Pet некоторые подвержены такому воздействию. Это видно по характерному помутнению горлышка. Судя по всему, составы пластика разные.

[@Not_Found_0]

Скорее всего эффект где-то уже описан в более расширенной форме, и учитывается производителями, но я, в силу своей безграмотности, безалаберности и отрыва от хим сообщества, вынужден быть кулибиным.

Отлично! а я мешать замучился вручную! у Вас пять балов!👍

How does it compare to PVA? I use a mixture of wood glue (which contains PVA) and water and don't need to heat my printbed when printing PLA. The adhesion in my experience is better compared to magigoo glue stick and even vision miner nano polymer (which seems to need a heated bed)! Only downside is it leaves white residue on the print, which PVP shouldn't? Also how often do you need to replace it? With wood glue/water mixture it lasts many prints, I only need to wipe it every now and then with warm water sponge to renew the adhesion.

[@V.Perinski]

PVP is a component used to make a wide range of adhesives. And yes, that glue leaves a white residue too, but it can be cleaned off. I don't know what PVA is made of. A glue stick is PVP+microcellulose for example.

[@trohn_javolta8485]

@@V.Perinski Update on this, finally tried it and the adhesion is horrible comapared to plain white woodglue on uneated beds. So yeah, back to simple wood glue for me :D

[@V.Perinski]

I don't know what PVA glue is made of :) And PLA plastic I very rarely use, it can basically be printed without heating the table.

[@V.Perinski]

@@trohn_javolta8485 The glue I made holds the parts so that I have to soak them in water along with the plate to get them off :)

hi, very good & simple video, what can be the other uses of PVP K-30? Can it be used as a water repellent for fabric water proofing? Is this adhesive? Pls reply, thanks

[@V.Perinski]

PVP K-30 (povidone) is most commonly used as a binder, film-former, and stabilizer in pharmaceuticals and cosmetics. It’s water-soluble, so it wouldn’t work as a water-repellent for fabrics - quite the opposite, it tends to attract and retain water. As for its adhesive properties, PVP does have some adhesive characteristics, which is why it’s used in certain types of adhesives (like in cosmetics or medical applications). However, for serious waterproofing or bonding tasks, other specialized materials are usually preferred.

[@IamAli89]

@@V.Perinski thank you for the detailed reply :), any suitable material you can suggest for waterproofing?

[@V.Perinski]

@@IamAli89 Hydrophobic liquids typically consist of chemical compounds that create a water-repellent layer on the surface of materials. The main components of such liquids often include: 1. Fluorinated polymers (e.g., polytetrafluoroethylene, known as Teflon) - these form an ultra-thin film that lowers surface tension, causing water droplets to roll off the surface. 2. Silicones (e.g., polydimethylsiloxane) - flexible and durable compounds that can form a strong hydrophobic film on various materials, including textiles. Silicone compounds have good water-repellent properties and can be applied as liquids or sprays. 3. Nanoparticles of metal oxides (e.g., silicon dioxide or titanium dioxide) - often part of nanohydrophobic coatings. These particles create a microscopically rough surface that minimizes contact between water and the material, enhancing the water-repellent effect. 4. Alkanes and alkylsilanes - hydrocarbon compounds commonly used in hydrophobic coatings to create a non-polar surface that repels water. These substances can work individually or in combination, forming micro- and nanostructures on the surface that prevent water from penetrating the material, causing droplets to bead up and roll off.

[@MrJoiny1]

I just received my Pen. Thank you for that recommendation. Would you say that it is better at sticking to or applying than the PVP Glue stick mixture?

[@V.Perinski]

In addition to the PVP itself, the glue stick contains other additives, perhaps microcellulose as a filler. And it leaves white stains on dark plastics. But PVP is completely transparent and you control the glue concentration yourself.

[@kennybeaudoin]

hello. are you sure this is the same product as in the link you are sharing ? the pvp from the link you shared is more powder kind of and in your video it is more like salt thank you

[@V.Perinski]

99% of the chemistry will remind you of salt :) But it's not ... I'm sure of what I'm sharing ...

[@kennybeaudoin]

@@V.Perinski yes i was just asking if the aliexpress link is the exact same material as you are using .. because the one i ordered from aliexpress link you give is more like powder :) thank you

[@V.Perinski]

Does it matter if you use K30 vs K90 PVP?

[@V.Perinski]

info in description. short: k90 more strong

[@whatisrokosbasilisk80]

Where did you buy your PVP from?

[@Alexx40in]

Очень, очень густо замешали. Для нейлона к90 замешивают 1:100, для остального еще меньше, 1:300 примерно. И без воды

[@V.Perinski]

Для спрея можно и жиже, для маркера самое то

[@Alexx40in]

@@V.Perinski это для маркера, как раз, указано. Для спрея сильно меньше

[@V.Perinski]

@@Alexx40in в описании я именно это и добавил. Себе сделал раствор как мне нужно было. А вы можете делать как нужно вам. Чего еще я должен добавить?! А вообще можно и без спирта. Прежде чем выдать ролик - были и другие эксперименты. Другими словами я показал свой метод, и повторюсь: вы можете делать раствор как вам нравится

[@NathanCroucher]

Superglue it never fails. Only need replace bed every print, and prints are unusable.

Is this some kind of joke?

[@paulystark2890]

Just use hairspray

[@V.Perinski]

Hair spray can contain polyvinylpyrrolidone (PVP) as an active ingredient. PVP is a polymer that is used in many hair products such as hairsprays, gels, mousses, and other styling and fixation aids. But in my example, you can use any concentration of PVP for use with different surfaces of a 3D printer.

[@paulystark2890]

@@V.Perinski Yes, a cheap can of Aqua Net only costs $2.99. It sprays on easy and comes off easy after the print with a paper towel and some rubbing alcohol for a nice clean bed. Rarely fails, works every time, cheap easy, no effort required, no mess, no fuss. Oh, and one can would last most people about a year since you only need a light fine mist to get good adhesion.

[@V.Perinski]

@@paulystark2890 I showed only my method and do not impose it. You can use what you like. I’ve tried a lot of things over seven years, and I liked this method the most.
